year and I hope you will enjoy reading about some of the highlights

in these pages. I particularly enjoyed my visit with Mary Marks

Wilcox (Class of 1942 Geology alumna) recently at her home in

Denver. She recounted wonderful stories about what it was like

being one of the only female geology students at that time, and

about her adventures with Ray Wilcox and their young family at

Paricutin volcano in Mexico in the mid 1940s. Mary has recently

made a very generous donation to the SEM lab in Ray’s name, and

we are deeply grateful for their support.

In fact, we are so appreciative of the support we (really our

students) receive from of every one of our many donors and

supporters. This year, I’d like to highlight a few specific funds

as especially timely, if you’d like to help but aren’t sure which of

the many boxes to check at the back of this issue. First of all, we

have the newly established Robert and Nancy Dott Geoscience

Fund, started by the Dotts as a family fund; contributions are very

much welcome from those to whom Bob and Nancy have been

mentors, inspiration and friends over the years. Second, in this

50th anniversary year of the Wasatch-Uinta Field Camp, assistance

for students to offset the costs of summer field would be a way to

directly help those in the same shoes you were likely once in not

so long ago! Finally, the Geoscience Fund is our most flexible one,

and we can use it to help students and researchers in myriad ways.

I want to close in remembering Lloyd Pray, who passed away this

year. A memorial is on page 20. I know that Lloyd was a great

scientist and teacher, and I know that many of you have memories

of all sorts of field and lab shenanigans with him. He was part of the

fabric of geology at Wisconsin and will be missed.

Enjoy this year’s edition of the Outcrop and Go GeoBadgers!

Harold Tobin

From the ChairDear Alumni and Friends,

As I write these words Phil Brown, Basil Tikoff, and the four

Geoscience 202 teaching assistants are preparing to take 85

students for the annual class field trip to the Black Hills of South

Dakota. This is no small undertaking: two coach buses with drivers,

three nights of camping and somehow cooking for all, and long

days learning which way is up in this introductory majors’ course.

But we all know there’s no substitute for getting out in the field,

and this class has become a hallmark of our immersive approach

to geoscience education. Field experiences like that are expensive.

Fortunately, thanks to the generosity of alumni who remember

similar experiences from their own student days, we can do this

with the Student Field Experience Fund.

In Weeks Hall, new labs are up and running, including Shaun

Marcott’s cosmogenic nuclide chemistry lab and Luke Zoet’s

walk-in freezer stocked with ice experiments. Argon-dating lab

renovations and updating of the newly named Wilcox SEM Lab are

underway as well. We have conferred a bumper crop of degrees

this year, with 15 Master’s degrees and 9 newly minted Ph.D.

geo-doctors (see pg. 8). Graduate students have been recognized

with numerous competitive awards, fellowships, and grants, while

undergraduates have been honored by UW for their research

proposals, projects, and service; read about all of these in these

pages.

Our faculty are national and global leaders in their fields. I want to

congratulate Alan Carroll for winning the Israel C. Russell Award

from GSA Limnology Division, Mike Cardiff for the Kohout Award

from GSA Hydrogeology Division, Steve Meyers for the James

Lee Wilson Award from SEPM, and Basil Tikoff for a Teaching

Award at UW. And finally, we are all particularly proud of Jean

Bahr, past President of GSA and now the 2016-17 President of AGI

(the American Geosciences Institute), the leading professional

organization in our field in the country.

I had a chance to say hello to many GeoBadger alumni in Houston

and Denver this year and fill you in on what we’re up to in

Madison, where (thankfully!) reports of the demise of higher

education at UW-Madison are greatly exaggerated. Budget cuts

have forced belt-tightening, and anti-university politics have

become a worrisome trend, yet we had another very productive

ment, industry, and as consultants, dealing with the environment, construction, petroleum, and mining. Our sister Board for Geological Engineering (GLE) has members with similar diverse career paths. We meet regularly with Department’s faculty, staff and students in Madison. We serve a four-year term and welcome nominations or expression of interest about being part of BOV.

Alumni support is more important than ever, due to reduced funding from the state, and challenges in funding research and teaching. Your generosity is instrumental in providing support for graduate research, teaching assistantships, and in keeping field camp and field trips affordable. Alumni support al-lows the Department and students to do much more than they could without it.

For example, your contributions this past year to the Student Field Experience Fund helped support 18 undergraduates in their 2016 Spring Break trip with Shanan Peters to the southern Appalachians and will be used to support 17 students on Brad Singer’s trip to Chile in January 2017.

Alumni have provided some large, and much appreciated, gifts this year to support graduate research. Jamie Robertson (PhD, 1975) established the James D. and Stella M. Robertson Graduate Fellowship as a 12-month research assistantship in Geoscience. Mark Solien (BS 1970; MS 1976; Distinguished Alumnus 2014) converted an existing graduate research support fund into a full-fledged endowment, the Mark and Carol Ann Solien Gradu-ate Research Assistantship. Rick Sarg (PhD, 1976) and Ann Sarg donated to the Lloyd C. Pray and J. Campbell Craddock funds. These gifts take advantage of the Nicholas Family Fund which matches 1:1 household donations of $50,000 or more, made over five years. This opportunity is still available, if you are able to give at this level.

Mary Wilcox and Family and friends recently donated funds to honor Ray Wilcox (BS 1933, MS, 36, PhD, 1941) to upgrade the Scanning Electron Microscope laboratory, which will now be named the Ray and Mary Wilcox SEM Lab.

I encourage you to contribute to the Department, and to utilize your company’s matching fund, if that is an option. See the last page of the Outcrop for the various funds. The department’s priority this year is the Field Camp Scholarship Fund and the Nania Fund

The Board of VisitorsChristine Griffith, Board Chair (2016-2017)It is an honor for me to represent the Board of Visitors for the Department of Geoscience, and by extension, all of the alumni of the Department of Geoscience. I’ve been a member of the Board for two years and am now the chairman. I am a petroleum geologist, recently retired from Shell Oil. I graduated with an MS in 1978.

This has been a great year for the Department. The 2016 Wasatch-Uinta summer Field Camp in Park City, Utah was very successful, with 65 students in at-tendance, 28 from the University of Wisconsin, which is more than twice the number of previous years. After the field camp, Park City hosted a reunion to honor the 50th year anniversary of the field camp. 30 alumni and their families enjoyed the scenery, com-radery, and excursions. Phil Brown deserves great credit for the success of the field camp and reunion.

We would like to congratulate several alumni who have achieved honors this past year: Marcia Bjorner-ud (MS, 1985, PhD, 1987), professor at Lawrence University in Appleton, WI, who became a Fellow of the Wisconsin Academy of Science, Arts, and Letters; John Eiler (PhD 1994) professor at California Institute of Technology, who was elected to the National Academy of Sciences; and the 2016 Department Distinguished Alumni mentioned on pages 4-5 of the Outcrop. Other alumni Board members are playing important roles in the geological societies this year: Claudia Mora (PhD, 1988), president of the Geologi-cal Society of America, and Rick Sarg (PhD, 1976), president of the SEPM Foundation.

Who are the Board of Visitors? We are a diverse group, who share the conviction that our educa-tion at UW was instrumental to the success we have had in our careers, and who want give back to the Department. We want help the Department to maintain their ranking as preeminent researchers and educators, and to provide current students with the experiences that will allow them to succeed in their careers. The Department of Geoscience Board of Visitors is one of many Departmental alumni groups at the University of Wisconsin, but we are credited with being one of the most involved and generous of these groups.

We have followed the diverse career paths as-sociated with geosciences: in universities, govern-

for graduate student support. Another worth-while option is to contribute to the Geoscience General Fund, which provides the Department the flexibility to respond to pressing needs, such as laboratory modernization. Our Development Director at the U.W. Foundation, Troy Oleck ([email protected]) is available if you want to discuss dona-tion options in more detail.

Thank you for your generosity, especially for graduate student support and for student field and field camp experiences. Your support makes a difference!

We on the BOV represent you, so we welcome your ideas about how we can further the mission of Department.

Distinguished Alumni Awards for 2016

For innovative and creative solutions to groundwater problems

CHARLES (CHARLIE) B. ANDREWS completed the PhD in 1978 with Mary Anderson after receiving the MS in Geology (1976) under David Stephenson, and the MS in Water Resources Management (1974). After leaving UW-Madison, he spent two years working with the Northern Cheyenne Indian Tribe (MT) to help set up a hydrologic monitoring program on the

reservation. Next followed four years with Woodward Clyde Consultants (CA) where he launched his career as a water-resources consultant. As Head of the Groundwater Section at Woodward Clyde, he oversaw the development of groundwater flow models in the Western US and the analysis of reservoir-induced seismicity at the Aswan Dam. In 1984, he joined the consulting firm S.S. Papadopulos and Associates, Inc. (SSPA, MD) where he served as President from 1994 until his partial retirement in 2012. He remains a Principal with SSPA and continues active involvement in projects including in Wisconsin where he is working with farmers and dairy operators to minimize the potential for nitrogen contamination of groundwater. Charlie is nationally known for thinking “outside of the box” and for his creative solutions to groundwater problems. He

Charles B. andrews, DistinguisheD Alumnus

For outstanding scholarship in sedimentary geology, especially for her pioneering work in tsunami sedimentation, in the history of geology, and for her excellence in teaching and mentoring students

has served on numerous advisory panels including for the U.S. National Academies, and the U.S. DOE, and as an associate editor for the international journal Ground Water. His expertise includes simulation of groundwater flow and contaminant fate/transport; evaluation of water resources/water rights; contaminated site investigations/groundwater remediation; and providing expert testimony/peer review. He has published the results of some of his work as book chapters, and articles in peer-reviewed journals and proceedings volumes. He is a registered geologist in six states and a Fellow of the Geological Society of America (GSA). He is currently a Trustee and the Treasurer of the GSA Foundation. He served on the Board of Visitors of our department from 2004 to 2012 and remains on the Board as a Senior Advisor. —Mary P. Anderson, Citationist

JOANNE (JODY) BOURGEOIS (PhD 1980) graduated cum laude from Barnard College of Columbia University, where she learned sedimentology from John Sanders. After graduating she spent two further years at Columbia as co-editor of the Encyclopedia of Sedimentology, which helped hone her excellent writing and editing

of Washington at Seattle (“that other UW”), where she has had a distinguished scholarly career as she realized her youthful goals of teaching, mentoring and conducting research in both sedimentary geology and the history of geology. Jody has been active in professional service in the Society for Sedimentology and Geological Society of America, including as a Councilor and an officer in the History and Philosophy of Geology Division, and in the Association for Women Scientists. Recently, she was recognized with the Laurence L. Sloss Award from the Sedimentary Geology Division of GSA. She also spent two years as the National Science Foundation’s Program Officer for Geology and Paleontology. Her Wisconsin graduate school alma mater feels honored by her stellar accomplishments and so takes pride in naming Joanne Bourgeois a Distinguished Alumna of the Department of Geoscience. —Robert H. Dott, Jr., Citationist

skills. In 1976 she chose Wisconsin for a PhD program based upon the reputation of our thriving sedimentary geology program and my interest in the history of geology. Jody was very active in departmental social activities, for example in helping to organize the Geosingclines. Her doctoral dissertation was on a Late Cretaceous sequence on the Oregon coast, a part of which she demonstrated was dominated by hummocky stratified wave deposits. From that grew her pioneering research on storm and tsunami deposits. In a landmark 1988 paper, she and her co-authors interpreted as of tsunami origin an anomalous coarse layer at the K-T boundary on the Texas coastal plain. This provided a kind of “smoking gun” for the Chicxulub impact site, which was identified shortly after, just across the Gulf of Mexico. She has since researched tsunami deposits from the Pacific Northwest to the Russian Far East and South America. In 1980 Jody joined the faculty of the University

O.B. SHELBURNE Orville B. “OB” Shelburne Jr. (M.S. 1956, Ph.D. 1959) parlayed his love of the stratigraphy and paleontology of sedimentary rocks into an outstanding career as a petroleum geologist with Mobil Oil. Under the direction of Professor Lewis Cline, OB honed his field geology skills through a Master’s project on central Texas stratigraphy and his doctoral dissertation

For outstanding contributions to sedimentary and petroleum geology

in the Ouachita Mountains of Oklahoma. OB was hired by Magnolia Petroleum as an exploration geologist in Oklahoma City in 1959, when oil sold for three dollars a barrel. Despite tough times in the oil patch, OB’s work ethic, dedication to excellence, and his focus on key objectives rapidly paid off. After Mobil Oil absorbed Magnolia, OB moved to the staff of Mobil’s Western Division Geologist in 1964 and served on Mobil’s Basin Analysis Teams from 1968 until 1972, when he moved to Denver as Chief Geologist for Mobil Alaska. A year later he moved again to New Orleans as Chief Geologist, then Exploration Manager, for Mobil’s critical offshore Gulf of Mexico business. Through his combination of geological and business skills he continued to rapidly advance at Mobil, and by 1987 was named General Manager for Mobil’s Worldwide Exploration and Production Services Inc. in Dallas, the top geoscience position within Mobil Oil. OB led the Worldwide E&P Services Center

until retiring in 1992 at age 60. OB is soft-spoken and not one to seek a spotlight for his achievements. Instead he let his solid geological and managerial skills speak for themselves. He helped navigate Mobil E&P through the oil price collapse during the early 80’s, successfully introduced E&P workstation technologies, and created attractive career paths for hundreds of Mobil geoscientists. Along the way, OB received a Distinguished Alumni Award from his undergraduate institution, Baylor University. Recognizing the importance of research assistantships for his own graduate work at U.W., in 2006 OB and his wife Rita established the Shelburne Research Assistantship Fund in the Department of Geoscience. The department and Board are proud to recognize OB Shelburne’s outstanding career as a petroleum geologist and greatly appreciate his continuing support for the Department of Geoscience. — Philip H.

Students in the FieldSpring Break 2016Blue Ridge Blues

Shanan E. PetersMany alums know the routine: Spring Break rolls around and a number of undergrads head out into the field to see some geology that they’ve read and heard about during the semester. This year was no exception. The trip started early Saturday morning with three department vehicles, loaded with people and guidebooks, and our trusty trailer in tow. Our first destination, Cedars of Lebanon State Park, on the east side of the Knoxville, Tennessee dome. After arriving safely and enjoying our first night in the field, the group saw Ordovician sequence stratigraphy along a fantastic roadcut, complete with the Diecke ash bed, and then headed into the Appalachian Basin proper, with a Chattanooga Shale and Fort Payne Chert exposure or two before hitting the Pennsylvanian fluvial deltaic sediments in the structure toe of the Appalachians. Our final destination on day two was the Ocoee River gorge, with well-exposed Precambrian sediments and a National Forest campground tucked along the river. From there we headed into the piedmont and a beautiful

and secluded National Forest campground in northern Georgia. That was the last regularly scheduled aspect of the trip! Turning north from Georgia along the Blue Ridge presented us with closures of key stretches of the Blue Ridge Parkway, closures of National Forest campgrounds (despite indications on websites that they were open!), and an ill-advised “shortcut” that required backing the trailer a long way down a one-track mountain trail. But, the group, Daniella Assing, Jonah Bastin, Justin C. Brown, Partick Callahan,

Connor Friese, Beau Howes, Erika Ito, Victoria Khoo, Zachary Lauridsen, Connor Lauzon, Derek Li, Cailee Luther, Zachary Olson, Parwat Regmi, Ryan Resch, Luke Schranz, Lauren Silverstein, Daniel Thompson rolled with the detours splendidly. We still saw the Brevard Fault Zone, the Grandfather Mountain Window, and a wide range of Blue Ridge basement rocks, from eclogites to biotite gneisses. A non-rock related highlight was a stop

in Korbin, KY to catch the men’s basketball team’s Elite 8 appearance. It was an enjoyable evening full of local color, which was capped by yet another gated National Forest campground! Call it a growing experience in every way, all made possible by the generosity of you, our alumni and the Student Field Experiences Fund. l

William J. LikosProfessor and Director of Geological Engineering ([email protected])

Greetings from Geological Engineering (GLE) at UW-Madison! This year has been marked by big changes and accomplishments from our students and faculty. Notably, we are making changes to our curriculum to add additional design content, including a new course in Applied Geological Engineering and have added new faculty to the program.

Our students continue to make us proud. Miles Tryon-Petith, who majors in geology, geological engineering and geophysics, was among 60 college students nationwide selected for a Udall scholarship in recognition of commitment to issues related to the environment or American Indian communities. GLE students Merve Gizem Bozkurt, Jiannan Chen, Hulya Salihoglu, and Kuo Tian wrote an outstanding article about Harry Poulos, a leading authority in

foundation engineering, that appeared in GeoSTRATA published by the American Society of Civil Engineers (ASCE). Graduate student Eleanor Bloom presented her research on sustainable systems for residential heating and cooling at a conference in Japan. We also made quite a splash at the ASCE GeoChicago conference held in Chicago in August, where over 16 presentations from UW-Madison students and faculty were given (see photo).

The job market for our graduates remains very strong, which reflects the strong nationwide demand for engineers (and the shortage of available engineers). Analysis from the Bureau of Labor Statistics indicates that anticipated growth in employment of mining and geological engineers remains greater than for other engineering occupations over the next decade. Our graduates have been receiving multiple offers with very competitive salaries. The dual GLE-Geoscience majors that our undergraduates obtain are extremely popular with employers. Indeed, this is a good time to be graduating from GLE!

In faculty news, Professors Tracey

GLEHolloway, Andrea Hicks, and Lucas Zoet joined as new GLE program faculty. Professor Holloway is affiliated with the Nelson Institute for Environmental Studies and conducts research on links between air quality, energy, and climate. Professor Hicks, who joined the Department of Civil and Environmental Engineering in fall 2015 as an assistant professor, specializes in quantifying the environmental impact of products and processes using life cycle assessment tools. Professor Zoet is a faculty member in the Department of Geoscience and studies glacial process through a combination of glaciology and glacial geomorphology.

Finally, please note that we are planning a special reunion for our Mining Engineering and GLE alumni from September 13-15, 2017. The reunion will be in the form of conference with guest presentations from alumni and friends. Please contact Ryan Shedivy ([email protected]) if you are interested in learning more about the reunion and stop by for a visit if you are in Madison. As always, feel free to reach out to me at [email protected] or (608) 890-2662. l

Geological Engineering faculty, students, and alumni gathered in downtown Chicago for a reception at the ASCE GeoChicago conference.


I entered the UW as a freshman in the fall of 1963. Courses from Lowell Laudon (Intro) and Bob Dott (Historical) convinced me that geology and not chemistry was my true calling. Bob Dott made fantastic chalkboard drawings of paleogeographic settings that first got me thinking about what the Earth used to look like. Advanced courses from Professors Dott and Cline in Madison, and Richard Paull at the UW-Milwaukee in my junior year added more background for my passion for Earth history. My MS at Utah (1970) with Professors Stokes, Eardley, and Robison continued to enrich my knowledge of Earth history and my PhD in 1973 from Iowa under guidance from Professors Furnish and Heckel continued the process. My PhD dissertation on the Triassic Moenkopi Formation of Utah contained my first paleogeographic maps—detailed pen and ink sketches of Utah’s Triassic landscapes.

After a brief stint at Fort Hays State College in Kansas, I arrived at Northern Arizona University in Flagstaff (1975) where I taught for almost 35 years. My early publications continued to be illustrated with pen and ink paleogeographic maps. Most of these were regional to the Southwest where I did most of my academic field work. The classic Dott and Batten textbook with its North American paleogeographic maps coupled with my growing interest of larger-scale Earth history and paleogeography broadened my interest in North American and global geology.

I learned the basics of Photoshop® in the 1990’s and saw the potential for making colored paleogeographic maps for any size region. I learned to clone and manipulate digital elevation maps, especially through GeoMapApp, a DEM mapping tool that can be combined with NASA’s Blue Marble, and soon I found I could create any type of landscape. By pasting or cloning the GeoMapApp landscape onto the foundations of a paleogeographic map (sea, land, shorelines,

The Archivist's CornerRon Blakey and the Ancient World

mountains, island arcs, etc.) and by manipulating color and other properties in Photoshop, I can adjust for climate, local relief, and other variable conditions. For example, I can clone the humid Appalachians and by changing color, contrast, and altering shape, I can “paint” the arid Mesozoic mountains of Southern Asia. At one point, I considered actually making oil paintings of ancient landscapes as I have painted with oils on canvas, mostly Western landscapes, for years. However, Photoshop is much less messy!

After retiring in 2009, I established a company through which I sell my maps to oil companies, museums, publishers, and other commercial businesses. I do all of the work of producing the maps from initial research to final map myself. It is not unusual for a single map time-slice to have over 50 hours of work in research, design, and production. My wife, Dee, runs the business. Maps are constantly updated or completely revised—I recently spent almost three years revising a new global map series with 47 time-slices from Late Precambrian to Recent. In addition to my current maps of North America, Europe, and the world, I plan to do maps of Australia, Southeast Asia, and possibly other regions. Many of my maps can be viewed on my new web site deeptimemaps.com. l

Alumnus Ron Blakey (BS 1967) is an

unusual geological entrepreneur. During his long

teaching career, Ron developed a series of detailed,

artistically realistic colored

paleogeographic maps, which

have become the gold standard for paleogeography.These maps are widely used in

textbooks, journal articles and oral presentations. His account of the development of the maps, with

roots of the idea in our Department, is

inspiring and should make us all proud of our fellow Badger.

In March, 2016, the UW-PoroTomo team performed field work at Brady Hot Springs, Nevada. The goal of the PoroTomo project is to assess an integrated technology for characterizing and monitoring changes in the rock mechanical properties of a geothermal reservoir in three dimensions with a spatial resolution better than 50 meters.

UW-Madison geoscientists and engineers are work-ing with industry partners and DOE to integrate sev-eral data-gathering approaches into a highly detailed monitoring system for geothermal wells.To fully realize the potential of harnessing energy from the heat within the earth will require a far more detailed understanding

of what’s going on down there than scientists currently have. And beyond naturally occurring geothermal systems, man-made ones that emulate them could, by some conservative estimates, produce a total of 100 gigawatts of cost-competitive electricity over the next 50 years. But to get there, energy providers will need sophisticated systems for gathering and analyzing data about the rock mechan-ics and hydrology at work. The PoroTomo project is funded by a grant from The Office of Energy Efficiency and Renewable Energy (EERE) of the U.S. Department of Energy. l

Wilcox Lab NamingJohn Fournelle

Thanks to a generous donation from Mary Wilcox and the Wilcox family, as well as from friends and colleagues, the Geoscience Department's Scanning Electron Microscopy (SEM) Lab will be named the Ray and Mary Wilcox SEM Lab.

Ray Wilcox (1912-2012) received his bachelor's degree in 1933, master's in 1936 and PhD in 1941. When he was a TA in mineralogy he met Mary Marks, who received her bachelor's degree in 1942. Ray ended up in the Signal Corps in World War II in the Aleutians, and by good luck was posted at a base on a volcanic island. The volcano erupted, and Ray helped a USGS geologist write up a recommendation for the Army. After hostilities ended, Ray joined the USGS and he and Mary (and son) moved near to Paricutin Volcano in Mexico, as the USGS observer. Later he worked on Aleutian volcanoes, and continued with

the USGS until retirement. At Wisconsin, Ray worked closely with R.C. Emmons (an icon in optical mineralogy and universal stage).

Funds raised will allow the SEM Lab to make a significant upgrade in improving the EBSD (electron backscatter diffracation) system which is a relatively new technique, wherein the specimen is tilted at 70° to the electron beam and electrons are diffracted into a sensitive detector, and the resulting "Kikuchi lines" are indicative of the crystal structure and orientation. l

Read Mary Wicox's personal account of "Living Next Door to Parícutin Volcano" in Mexico in 1946. Her story was feaured in a

1998 Outcrop article about Badgers in the Aleutians, on page 9.

Introduction and Background

Alexander Newton Winchell (1874-1958) was professor of geology at the University of Wisconsin from 1908 to 1945. He came from an old and illustrious family traceable back to some of the first colonists of North America. One branch (Windsor) of the family emigrated from Great Britain to Massachusetts in 1635. Much later, the well-known geologist Alexander Winchell (1824-1891), who was A.N. Winchell’s uncle, was born in Duchess Co., New York. A. Winchell moved to the state of Michigan and began a professional academic career at the University of Michigan in 1854 and he became professor of geology and paleontology and then the second head of the Michigan Geological Survey in 1859. Newton Horace Winchell (1839-1914), the father of Alexander Newton, followed his elder brother Alexander to Ann Arbor and studied there obtaining a M.A. in 1867. He was appointed director and state geologist of the Geological

and Natural History Survey of Minnesota in 1872, a post he held until 1900. He also taught at the University of Minnesota. They must have been pretty heady times in terms of geology, as under their guidance and through their own research, the two Winchell brothers carried

out some of the first detailed mapping and geologic investigations of the Upper Midwest.

Into this family and background A.N. Winchell was born in Minneapolis. He majored in history as an undergraduate at the Univer-sity of Minnesota in 1896. The family tradition must have been strong, though, because his M.S. (1897) there was in geology. Fol-lowing this, he went abroad to Europe and worked with the famous mineralogist and petrographer Alfred Lacroix and he obtained his D.Sc. from the University of Paris in 1900. The thesis title was “Étude minéralogique et pétrographique des roches gabbroiques de L’État de Minnesota.”

Professional Career and the Birth of Modern Mineralogy

A.N. Winchell returned to the U.S. as professor of Mineralogy and Petrology at the Montana School of Mines working there from 1900 to 1907. In the latter year he was appointed to the Faculty of Geology at Wisconsin, well known for its strength in “hard-rock” petrology with the persons of R.D. Irving, C.R. Van Hise and C.K. Leith, and also for the geologist T.C. Chamberlin. A.N. Winchell turned out to be very productive and his geologic interests were

extremely broad. He undertook field studies and he published numerous reports and pa-pers in economic geology and igneous and metamorphic petrology. His main interests and expertise, though, were in mineralogy and especially optical mineralogy and in the latter he gained worldwide recognition. His books and tables treated the optical properties of minerals, as published in three different volumes, and they covered four editions spanning 42 years.1 The first edition of “Elements of Optical Mineralogy” (1909) was written together with his father, N. H. Winchell, and the last fourth version in 1951 together with his son Horace Winchell, who was professor of mineralogy at Yale Univer-sity. Thin section and grain-mount examina-tion were important methods for many years in mineralogy, petrology, economic geology and geochemistry and the compositional determination of minerals was mainly done through study of their optical properties.

A.N. Winchell worked during a remark-able period when the physical sciences were undergoing revolutionary developments. A

The six common silicate garnets - starting at the upper left and going clockwise, uvarovite, grossular, andradite, pyrope, spessartine, and almandine (photo credits in Geiger, 2016) - were proposed to belong either to the ugrandite and pyralspite species by N.H. Winchell and A.N. Winchell (1927). This classification, which was based on the known solid-solution behavior at the time, is, however, no longer considered strictly valid (Geiger, 2016). Natural silicate and various non-silicate synthetic garnets find important uses and applications as gemstones, for geothermobarometry studies, index minerals in diamond exploration, ion conductors, magneto-optic materials, and lasers.

Alexander Newton Winchell and the Modern Mineral Sciences

A.N. Winchell


key breakthrough in solid-state investigations was given by the discovery of X-ray diffrac-tion by crystals in 1912 by M. von Laue and colleagues in Germany and crystal structure analysis soon after by W.H. Bragg and W.L. Bragg in Great Britain. These two discoveries marked the beginning of modern mineralogy or “The Mineral Sciences” today. The scientific consequences were deeply fundamental. This is because a quantitative understanding of the chemical and physical properties of minerals, or any crystal for that matter, is only pos-sible from knowledge of the periodic spatial arrangement of their constituent atoms (i.e. crystal structure).

Various scientists, some of great renown, had been discussing and debating from the late 1700s and early 1800s about the internal structure and solid-solution behavior (or isomorphism as it was formerly termed) of minerals and other substances (Geiger, 2016). The majority of the important rock-forming silicates (e.g., olivine, pyroxene, mica, amphibole, feldspar, garnet – see photo) that make up Earth are solid solutions and their properties have profound effects on large-scale geophysical and geochemical processes. The precise nature of silicate solid solutions at the atomic scale was not understood,

though, even into the first half of the 1920s. A.N. Winchell, though a classical mineralogist and petrographer by training, was one of the first to recognize the connection between atoms, crystal structures and solid-solution behavior and he published an article in 1925 in the journal Science entitled “Atoms and Isomorphism” in which he presented his ideas. Winchell began his analysis with the statement, “Atoms were formerly known only by their weights and chemical properties. …. I shall try to show that one of the properties of atoms depends upon their sizes rather than their weights.” Although a seemingly elementary concept today, which is learned in high-school chemistry courses, an understanding of atomic and ionic radii of the elements did not become fully clear until the mid 1920s. It is the size of ions in silicates that largely determines their solid-solution behavior. In 1934, at the ripe old age of 60, A.N. Winchell took a semester sabbatical to work, in part, with Linus C. Paul-ing, a later two-time Noble prize winner at The California Institute of Technology, in order to learn more about the new scientific field of X-ray diffraction. They published together a paper on the crystal structure of swedenbor-gite, NaBe

4SbO

7 (Pauling et al. 1935).

Among various positions and duties in his

career, A.N. Winchell served as Chairman of the Department of Geology at Wisconsin from 1934 to 1940. He was president of The Miner-alogical Society of America in 1932 and he was presented with its highest achievement award, The Roebling Medal, in 1955. (Kerr, 1956) reviews briefly A.N. Winchell’s career and lists his various works. Memorials to him were writ-ten by Corbett (1959) and Emmons (1959) and his role in the Department at Wisconsin can be found in Bailey (1981).

Understanding the mechanics of faulting and earthquakes is a key goal of a range of geoscience research. Until recently, research focused on this fundamental problem of both scientific and societal interest has been domi-nated by geophysical and paleoseismologic approaches. Exploitation of the deeper rock record of earthquakes, including exhumed ancient earthquake source regions, has been hampered by disagreement about which structures actually record earthquakes as well as limitations in the geochronologic tools available to quantify timing of seismic failure. Recent insights and innovations have allowed us to overcome these obstacles. In this progress report, we highlight UW-Madison’s contributions to understanding the deeper earthquake record through the integration of structural and geochronologic approaches.

Our report is divided into two parts. The first part is focused on pseudotachylyte - the spectacular product of frictional melting that constitutes the sole geological structure in the rock record universally agreed to record fault slip at seismic strain rates (Cowan, 1999; Rowe and Griffith, 2015). This research instigated, and has greatly benefited from, an upgrade to the WiscAr geochronology lab in Weeks Hall (http://geochronology.geoscience.wisc.edu/). We therefore share both our results and information on the UV laser that was recently added to the WiscAr facility, which is par-ticularly well suited to study of fine-grained, heterogeneous fault rocks. The second part of our article reports on research into a very different record: calcite veins that record co-seismic fracture opening and post-seismic sealing in a high-angle normal fault in an extensional basin. Both projects have involved teams of researchers, from graduate students to external collaborators, who we formally recognize and appreciate below.

Ages of earthquakes in the damage zone of the South Mountains detachment

In 2012, Goodwin (with Professor Josh Fein-berg, Univ. of Minnesota) was awarded an NSF EAGER grant to evaluate a critical earthquake record: numerous pseudotachylyte fault or

generation veins and, local-ly, injection veins preserved in the damage zone beneath a low-angle normal fault, or detachment, in the South Mountains, AZ. EAGER grants provide seed funding for demonstrably high risk but potentially transforma-tive research. Our project addressed the fundamental question of whether low-angle normal faults produce significant earthquakes, which the current fault me-chanics paradigm indicates should not occur. Dating of veins was completed in the WiscAr lab. There was a real possibility that

Pseudotachylyte generation (g) and injection (i) veins cut granodiorite mylonite in damage zone of the South Mountains detachment fault. (Jack Hoehn)

Back-scattered electron images of two pseudotachylyte veins analyzed and adjacent wall rock show the location, size, and shape of UV laser spots. Spots have been color coded to show age distributions, with older pseudotachylyte ages recording contamination by survivor clasts. All laser ages collected to date are shown.

READING THE ROCK RECORD OF EARTHQUAKES

pseudotachylyte formation could not be dated. Depending on the temperature of the wall rock at the time of failure, the veins might record either near-instantaneous quenching or subsequent cooling. Because the veins include ‘survivor clasts’ (unmelted chunks of wall rock, variably degassed during melting), glass (commonly low retention of argon), and 1-10 µm sized new grains crystallized from melt, sample preparation for standard step-heating analysis is challenging. Intrepid alumna Dana Smith took on the work as part of her MS degree (Smith, 2013), carefully separating shards of pseudotachylyte that lacked visible survivor clasts and working with WiscAr lab guru Brian Jicha to conduct analyses. The result? Jackpot! Different veins from the same outcrop yield different ages, thus recording times of quenching, rather than a single time

of outcrop cooling.Concerns about the accu-

racy of the dates, however, were stoked by a duplicate effort using a UV laser in col-laborator Matt Heizler’s lab, which suggested an injec-tion vein Dana dated actually records two slip events. Last year, with PhD student Jack Hoehn on board, we submitted an additional NSF proposal to study a much larger number of veins in greater detail. Motivated by the potential of the project, Singer secured funds to purchase a UV laser that would allow us to quantita-tively evaluate the impact of survivor clasts too small to see with a binocular scope.

We are pleased to report that the laser is up and running and our proposal was successful. With major efforts by Jack and Brian, we have recorded four episodes of seismic slip during a period of more than three million years, consistent with Wernicke’s (1991) proposal that low-angle normal faults can produce significant earthquakes, but only at very long intervals.

Periodic earthquakes recorded by calcite veins in the Loma Blanca normal fault zone, NM

UW post-doctoral fellow Randolph (Randy) Williams, who recently completed his PhD in the department (2016), has been working with Goodwin and collaborator Peter Mozley of New Mexico Tech to better document the hydromechanical evolution of faults in the Rio

Grande rift of New Mexico. In a paper recently accepted by the Geological Society of America Bulletin, Williams, Goodwin, and Mozley documented evidence that veins restricted to zones of overlap (i.e., relay zones) be-tween adjacent segments of the Loma Blanca fault record coseismic tension. These veins commonly contain crack-seal microstructures, recording multiple fault slip-

induced fracture opening and sealing events. Veins that form regularly oriented sets exhibit a stable isotope signature of mixing of deep basinal brines and meteoric fluid (Williams et al., 2015). Veins associated with breccias –such as that shown on the cover of The Outcrop - are isotopically distinct and include a carbon isotope signature of degassing of either CO

2 or CH

4.

Randy worked with Warren Sharp of the Berkeley Geochronology Center to collect U-Th dates on both veins that are associ-ated with breccia and veins that are not. The sampling strategy assumed that the cements precipitated early in vein history would ap-proximate the timing of a given earthquake. The data show that veins that form sets that are not connected to breccia zones record remarkably regular earthquakes, occurring every ca. 40 ± 7 ka over a >400,000 year period. The breccia zones record a cluster of earthquakes that overlap within analytical uncertainty, but the isotopic signatures of dif-ferent events are distinct. We hypothesize that this cluster records a period of elevated pore fluid pressure.

As data from the two field areas demon-strate, these approaches to dating the rock record of earthquakes allow us to evaluate histories much longer than those available through traditional paleoseismic studies. We think this work is both timely and fascinating, and believe the integration of structural and geochronologic analyses of fault rocks will allow us to move beyond a documentation of the pattern of seismicity, toward a better understanding of the mechanical processes that control earthquake recurrence.

On April fifth this year our esteemed col-league, Professor Emeritus Lloyd Pray, died at the age of 96. Poignantly, his wife of 70 years, Carrel, died only 54 days later. They are survived by four sons and 12 grandchildren.

Lloyd will be long remembered for his boundless enthusiasm and a genius for inspiring and mentoring the many students who came under his spell. Since retiring in 1989, Lloyd and Carrell continued to live at Tumbledown Farm in their beautiful old stone farmhouse just west of Madison. They en-joyed interludes at a cottage on the shore of Lake Superior near Ashland where Lloyd had grown up. Of course he continued to conduct some field trips to his beloved Guadalupe Mountains in southeastern New Mexico until it became physically prohibitive.

Lloyd graduated cum laude from Carleton College in 1941 and earned an MS from California Institute of Technology in 1943. He then enlisted in the Navy and worked on surveys of Japanese harbors to assess their navigability in case of an invasion. He married Carrel Meyers in 1946 and returned to Cal Tech to complete the PhD in 1951. His disser-tation concerned the Paleozoic stratigraphy of the Sacramento Mountains in New Mexico.

Pray taught at Cal Tech for five years before moving to Denver to join the newly formed

Marathon Oil Company research laboratory in 1956. There he initiated a carbonate rock research program and became a leader in a small, dynamic group of carbonate workers, which formed a remarkably fruitful collabora-tion. This group was dominated by members of petroleum industry research programs like Lloyd’s, but it had a very positive impact upon academic sedimentology. The Society for Sedimentology (SEPM) provided a forum for the rapidly changing field of carbonate sedi-mentology and Lloyd was right in the midst of Society affairs, becoming President in 1969.

It was also in 1969 that Lloyd succumbed to the persuasion of Professor Lewis Cline to re-enter academia and join our Badger fold. While teaching an undergraduate summer field course, Cline recognized student Pray’s potential and had kept him in his sights. By

the time Lloyd joined us, he had an interna-tional reputation, which gave our sedimentary program a significant boost. His industry experience gave a valuable extra perspec-tive to his teaching. Within a few years the Wisconsin program was being ranked among the top two or three in the country. We were also blessed with many top-notch students, who in turn have risen to prominence in both academia and industry. All of them owe much to Lloyd Pray.

Lloyd was a gifted teacher. His infectious enthusiasm, humor, and outgoing personal-ity captivated all. In 1988 he was awarded a coveted UW Distinguished Teaching Award to add to an already long list of honors. These included the Twenhofel Medal, sedimentary geology’s top award (1999), the AAPG Matson Award (1967), SEPM Honorary Membership (1982), and an AAPG Distinguished Lecture-ship (1985-87). Perhaps he was most proud of a 1988 Guadalupe Mountains National Park Citation for his many contributions to the understanding of that fabulous region.

Lloyd’s most important single contribution was his leading international role in promot-ing carbonate sedimentology. More specific contributions to the field included the co-authorship of a very influential classification of types and evolution of porosity in carbon-ate rocks. Then there was the recognition of syndepositional marine carbonate cements when conventional wisdom ruled them to be impossible; the recognition that many sup-posed shoal water “patch” reefs were actually allochthonous megabreccia blocks formed by submarine debris flows; recognition of phylloid algal buildups and the demonstration of their petroleum reservoir potential; and the elucidation of so-called Waulsortian reefs. Lloyd was fond of challenging conventional wisdom with maverick hypotheses, which was the theme of his SEPM presidential address.

Pray was an evangelist for field geology. He led popular field trips, which became legendary especially those to the Guadalupe Mountains to study the famous Permian reef complex. Outcrops-by-headlights and jump-ing-jacks-at-the-first-stop after a cold night sleeping on frozen ground are remembered fondly by many. Douglas Pray, Lloyd’s young-est of four sons, filmed Lloyd’s last UW field

A Tribute to Professor Lloyd C. Pray (1919 - 2016)

A Special Symposium “Honoring Lloyd C. Pray” will be held at the 2017 AAPG/SEPM meeting in Houston. The meet-ing will be organized by Rick Sarg and Bill Morgan who dedicate it as a tribute to Lloyd’s many contributions to carbonate geology—from cements and pore systems to buildups, slopes, and allochthonous deposits. As usual, the Department will host a social event for alumni; Rick and Bill will further highlight Lloyd’s contributions there.

trip to the Guadalupe Mountains in 1988. That film, The Stratigraphy of a Geologist, is avail-able through SEPM and provides a valuable teaching device portraying Lloyd’s captivating talents and his geological philosophy. He also led many trips there that were connected to professional meetings and he participated in many symposia and short courses. Lloyd also conducted important research in the Canadian Rocky Mountains, in Spain, and in Libya.

Well remembered are Pray’s stimulating lectures and imaginative laboratory exercises. A bowl of corn flakes or potato chips vividly conveyed the complex fabric of phylloid algal limestones and macaroni of varied shapes immersed in epoxy showed how fossil shells could seem to be free-floating in a random

thin section. Then there was “bad water,” which seemed to account for all manner of carbonate depositional and diagenetic mysteries. Most important of all, however, is the testimony of numbers of former students that “Lloyd taught us how to look at rocks.” One day a few years after he had retired, Lloyd poked his head into the carbonate lab to find all of the students squinting at their computer screens. I heard him exclaim “Doesn’t anyone look at rocks here anymore?”

Lloyd’s international reputation naturally attracted some post-doctoral fellows. Notable among these were two young Spanish geolo-gists, Mateo Esteban and Antonio Simo, who collaborated with Lloyd for several years. Simo

was chosen to fill Lloyd’s faculty position as our carbonate man until he was lured to industry in 2006.

The citation for Lloyd’s Twenhofel Medal award, which was presented appropriately by one of his early protégées at Marathon, then president of SEPM Harry E. Cook, read as follows:

To Lloyd C. Pray for his memorable and sustaining accomplishments in under-standing the origin and relevant char-acteristics of many aspects of carbonate sedimentary rocks, and for being a joyful, trustworthy, and caring person to his fami-ly and friends, his students and colleagues, and the geological community.” l

In MemoriamCarrell Pray passed away in Madison on May 27, 2016 at the age of 96, just 54 days after her husband Emeritus Professor Lloyd Pray's passing. Carrel is best known in Madison as the founder and first director of the Madison Boychoir, which eventually became today's Madison Youth Choirs. Carrell met her future husband Lloyd on a train to Washington, D.C. and they were married for 70 years. Well respected in Wisconsin as a watercolorist, her paintings were exhibited throughout the region. She helped start a camp for diabetic children, was host to foreign AFS students, was an avid tennis player, an active member of the Religious Society of Friends (Quakers), and supported political causes and promoted social justice. She is survived by four sons, 12 grandchildren, and three great-grandchildren.

Louise Clark, wife of Professor Emeritus Dave Clark, passed away in Provo, Utah on April 12, 2016 after a 50 year struggle with the complica-tions of rheumatoid arthritis. She was an active member of the LDS church, and was selected as Wisconsin’s Mother of the Year in 1997. She lived in many cities but spent most of her life in Madison, where she lead support groups for those with auto-immune diseases and taught medical students at UW-Madison about living with rheumatoid arthritis. She is survived by her husband David, a son, two daughters, 16 grandchildren, and six great-granddaughters.

Dorothy "Dottie" Craddock, wife of the late Professor Campbell Craddock, passed away on September 16, 2016 in Roseville, MN at the age of 86. She graduated from Millikin University in Decatur, IL, and attended graduate school at UW-Madison. She married J. Campbell Craddock in 1953. Dottie and Cam lived in New York, Texas, New Mexico, Wyoming, New Zealand, and Minneapolis, and then settled in Madison in 1967. Cam was Professor of Geol-ogy at UW-Madison for 40 years while Dottie taught elementary school. The Craddocks moved to St. Paul in 2006 and Cam passed away on July 23, 2006. Dottie is survived by three children and eight grandchildren.

John Dennison, PhD 1960 University North Carolina-Chapel Hill Emeritus Geology Professor, Dr. John Dennison passed away on June 2, 2014. He earned his Ph.D. in geology at UW-Madison in 1960 under Lew Cline. He taught at the University of Illinois, the University of Tennessee, and finally, from 1967 until 2002, at the University of North Carolina in Chapel Hill. His investigations were varied, but focused on the strata of the Appalachians from Alabama to New York and their associated fossils, mineral resources, and the geologic history of their developing struc-tures and topography. His research spanned over half a century of scientific publications, more than a hundred in number. He humbly received many professional honors.

Gwendolyn M. Schultz, writer, and Professor Emerita of Geography at the University of Wisconsin-Madison, passed away on March 15, 2014 in Milwaukee at the age of 91. As a geog-

raphy professor on the UW-Madison campus, she served in several departments, instructing, writing, doing research and cartography and, later, with Wisconsin Geological and Natural History Survey.

Charles D. Reynolds passed away on September 25, 2015 in Pittsburgh, PA. He was a graduate of the UW-Madison, a WWII veteran of the U.S. Army Corps of Engineers and spent his entire career traveling the world with U.S. Steel as a geologist. He was a founding member of The International Marine Minerals Society (IMMS).

Justin R. Brown, BS 2006, passed away in August 2016. "A bright light in every way," on this cam-pus he was a UW-Madison Chancellor Scholar, an Undergradu-ate Research Fellow, and an Under-graduate Hilldale Scholar. From our department he received the Distinguished Undergrad award in 2004, the Hanks' Award in 2005, and the T.C. Chamberlin Scholarship in 2006. At the time of his death he was Visiting Assistant Professor of Geophysics at James Madison University. He is survived by many loving friends family mem-bers, and colleagues. Justin is remembered as warm, funny, and brilliant. l

Faculty News —2015-16JeAn BAhrInternational travels were a highlight of the past year. In June I visited Switzerland and Belgium with a delegation of the Nuclear Waste Technical Review Board. In addition to enlightening discussions with researchers and regulators in both countries, we were able to go underground in three research laboratories: the Grimsel crystalline rock lab and the Mont Terri clay lab in Switzerland and the Hades clay lab in Belgium. We all came away from those visits convinced that long term experiments in such underground facilities are a critical component to designing a robust geologic repository for high level waste. In July I attended the Int. Assoc. of Hydrologic Sciences GQ16 conference in Shenzhen, China, organized by UW alumnus Chunmiao Zheng. The conference focused on safeguarding groundwater quality in a changing world. The location in a metropolitan area that has grown from less than 30,000 in 1979 to over 20 million people today highlighted the chal-lenges of providing adequate clean water to the world’s megacities. Back in Madison I continue to enjoy inter-acting with students in classes and in research. M.S. student Hangjian Zhao successfully com-pleted his double degree with Water Resources Management in August and has recently moved to the Twin Cities. Josh Olson and Elisabeth Schlaudt, also in the WRM double degree track, made good progress on their research and will be presenting papers at the upcoming GSA meeting in Denver. Madison Larkin, who began her graduate studies last fall, is examining long term plume evolution at a site on the Bad River Reservation. This fall I am looking forward to sharing the hydrogeology course with Mike Cardiff. Enrollments in that course continue to grow, driven, in part, by the high enrollments in the Geological Engineering major. Sharing the course with Mike will facilitate some upcoming meeting travel associated with my term as presi-dent of the American Geosciences Institute. I’m particularly looking forward to an AGI Critical Issues Workshop in October that will delve into issues associated with management of the high plains aquifer and, more generally, aquifers that span multiple legal boundaries.

michAel cArdiFFIt was my 4th year as faculty here at Madison, but the 2015-2016 academic year continued to bring its fair share of “firsts”. My first PhD, Yao-

Quan Zhou (PhD 2016), successfully defended her doctoral thesis in May 2016, after four years of hard work on lab experiments and numerical modeling. YaoQuan’s hard work also helped produce my group’s first student-led paper in the journal Water Resources Research (Zhou et al. 2016). Masters student Claire Sayler (MS, 2016) also successfully defended her thesis this past year, and then quickly became my first student to say goodbye and “leave the nest”. Claire has now taken a position in Washington, DC at the venerable environmental firm S.S. Papadopulos & Associates. While my first students are wrapping up their work and beginning to make their way in the world, new blood and new projects con-tinue to produce interesting research problems. Working with my continuing student David Lim (MS, 2016), my group is taking its first foray into the hydrogeology of geothermal systems, through the DOE-funded PoroTomo project led by Kurt Feigl. Throughout March, we spent a month at an operational geothermal site in the Nevada desert (a nice break from Madison winters) listening to the reservoir with an array of satellites, seismics, and other sensors. In a related but smaller-scale project, student Ben Heinle is working on the first lab experiments that will enable visualization of heat movement and exchange in fractures, providing insights into the energy movements in geothermal reser-voirs. Finally, thanks to a nomination by Jean Bahr, I was honored to receive my first award made out of actual rock. During the 2015 Fall GSA meeting, I accepted the GSA Hydrogeology Division Kohout Early Career Award (accompa-nying a very nice fossiliferous limestone trophy)(photo, page 14). Many thanks are due to the people around me—my students, colleagues, and the extended community of Weeks Hall—who I couldn’t have done it without!

AlAn cArrollOver the past year I have continued to develop my interests in energy education and outreach, with the overarching theme that everything we do in this area involves finite Earth resources. Since my book was published in March 2015 (see last year’s Outcrop) I’ve had a number of interesting opportunities to address the public, ranging from the Wisconsin Society of Profes-sional Engineers to the Larry Meiller radio pro-gram. Perhaps the most stimulating was a talk I gave at the University of Utah, where a group of

faculty had proposed that the University divest its holdings in fossil fuel companies. It turned out that all parties were in complete agreement regarding the urgency of the climate change, but there were passionate disagreements over what should be done about it, and whether divestment would have any real impact on carbon emissions. It is without doubt a complex problem, and the Utah faculty eventually voted to recommend divestment by a narrow margin (note that UW-Madison addressed this question several years ago, with the opposite result). Back in Madison I have continued experimenting with online and blended learning approaches to teaching. I “flipped” my Energy Resources class (Geoscience 411), delivering lecture material online and using the class time instead for discussion with smaller groups of students. I also taught a three-week version of this course to about 30 students during June 2014, using the high-quality videos that were produced for the the MOOC (Massive Open Online Course) that I taught in the summer of 2015. I can also report several new milestones on the research front, starting with the publication of a special volume on the Green River Formation co-edited by former student Mike Smith and myself. This vol-ume provided an opportunity to finally get some student papers published that had lain fallow, including excellent contributions by Mike Smith, Brooke Norsted, Jennifer Graf, and Meredith Rhodes. M’Bark Baddouh completed his Ph.D. (co-advised by Steve Meyers), and published an innovative paper on the use of 87Sr/86Sr to track continental-scale moisture circulation patterns in the Eocene. Marshal Tofte completed an M.Sc. thesis that examines regional patterns of organic enrichment in the Bridger basin, based on thousands of Fischer Assay measure-ment of oil shale potential. Unsurprisingly, the petroleum industry employment picture for our graduates has been much more challenging the past couple of years, but there are suggestions that it might be starting to improve.

chuck demetSThe past year was a productive year for complet-ing papers, proposals, and research, making it nearly ideal from a professional standpoint. The highlight of my year was a month-long research visit to Ecole Normale Superieure on the Left Bank of Paris to work with two French col-leagues at ENS. A quiet office overlooking a park and my proximity to some of Paris's best cafés



and quietest streets were key ingredients for a productive and relaxing break from Madison. My graduate students Andria Ellis and Beatriz Cosenza spent the year continuing their model-ing of the earthquake cycles of western Mexico and northern Central America. Hopefully, their work will come to fruition and be published during the coming year. My decade-long plate tectonic research project with long-time col-laborator Professor Sergey Merkouriev of St. Petersburg State University yielded four more published papers during the past year, one of which we believe has important implications for geological and structural interpretations of the geotectonic evolution of the western U.S. and Canada for the past 20 Myr.

kurt l. FeiglHélène Le Mével completed her PhD thesis on the Laguna del Maule volcanic field on the crest of the southern Andes. In her final year, she de-veloped, from first principles, a dynamic model to explain the exceptionally rapid deformation there. As of March 2016, rate of vertical uplift was still faster than 200 mm/yr, as it has been since some time before 2007. In March 2016, the PoroTomo team per-formed field work at Brady Hot Springs, Nevada. From UW-Madison, Neal Lord, Xiangfang Zeng, Chelsea Lancelle (PhD 2016), David Lim, Lesley Parker, Mike Cardiff, Cliff Thurber, Herb Wang and Dante Fratta (GLE) joined me in working long hours under demanding conditions for 26 days in a row. The whole operation felt like a mountaineering or sea-going expedition. Elena Reinisch, Tabrez Ali, Michelle Szabo, Judy Gosse, and Dan Koetke (OQI), provided invaluable logistical, financial, and moral support in Madison. The PoroTomo team also includes scientists and engineers from Ormat Technologies, Silixa Limited, the University of Nevada-Reno, Temple University, Lawrence Livermore National Labora-tory, and Lawrence Berkeley National Labora-tory. Thanks to their strong work, we success-fully collected more than 55 Terabytes of data, while braving howling sandstorms, monitoring interstate traffic, surveying avian nests, chowing plastic breakfasts, imbibing truckstop coffee, en-countering enterprising mice, hearing turbulent flow, watching steaming fumaroles, avoiding archeological sites, juggling digital radios, and consuming energy bars. I thoroughly enjoyed the combination of non-stop problem-solving and story-telling as we commuted between our “lab” (a 40-foot shipping container), our “living room” (another 40-foot shipping container),

and our motel (no comment) in Fernley. With the (awfully long) title of “Poroelastic Tomography by Adjoint Inverse Modeling of Data from Seismology, Geodesy, and Hydrol-ogy”, the PoroTomo project aims to assess an integrated technology for characterizing and monitoring changes in the mechanical properties of a geothermal reservoir in three dimensions with a spatial resolution better than 50 meters. A better understanding of the hydrologic, mechanical, thermal and chemical processes will contribute to realizing the poten-tial of harnessing energy from the heat within the earth. The PoroTomo project is funded by a grant from The Office of Energy Efficiency and Renewable Energy (EERE) of the U.S. Depart-ment of Energy

John Fournelle2015-16 continued to be busy with getting the new CAMECA SXFive FE electron probe operational. I was invited to give a series of lec-tures at Nanjing University in November 2015, on electron probe microanalysis, particularly dealing with applications in geoscience. I also gave lectures at the University of Science and Technology of China at Hefei and at the Chinese Academy of Geological Sciences in Bejing. China has changed a lot since I visited there 37 years before! It turned out that our own Sturgis “Bull” Bailey had been at Nanjing University in 1985, giving a clay mineralogy short course, where a young graduate student by the name of Huifang Xu would be in the audience and decide to take up mineralogy (see p. 12 in the Outcrop for 2014-15). In March I gave a lecture on low voltage electron probe microanalysis at the University of Lausanne. I was the local organizer for a successful international electron probe mi-croanalysis conference, held here at UW in May. This summer, Phil Gopon (MS 2010) success-fully defended his PhD thesis and headed off to do a postdoc at Oxford University. Aurelien Moy (Université de Montpelier, France) started in August to work with me as an NSF-funded postdoctoral fellow, helping to continue the low voltage electron probe microanalysis research which Phil and I started.

lAurel goodwinIn the past year, I received research grants from both the Petroleum Research Fund (with Co-PI Peter Mozley of New Mexico Tech) and the National Science Foundation (with Co-PIs including our own Brad Singer as well as Josh Feinberg of the Univ. of Minnesota). The suc-cess of these proposals is rightfully shared, not only with graduate students Randy Williams

and Jack Hoehn and alumna Dana Smith, whose preliminary research formed the center-pieces of these proposals, but also with alumni who, through the Leith Fund, have provided a steady drumbeat of support for UW-Madison’s structure program. Basil Tikoff and I have used interest earned on the Leith Fund for everything from graduate and undergraduate student fieldwork and analytical fees to equip-ment purchase and repair. This seed money has played an increasingly critical role as funding rates from all sources that support geoscience research have declined. This Outcrop summary and, really, all of the summaries we write should be viewed as thank-you notes to our alumni. We would be so much less without you. These days, my research group is all about earthquakes and the record they leave in fault rocks, from the high- and low-angle normal faults that are the focus of this year’s cover article to a subduction zone thrust fault. Randy, who successfully defended his dissertation Au-gust 15 and is now officially Dr. Williams, post-doc, will continue to focus on the normal fault record of fluid flux, including coseismic calcite veins that record the timing of fracture opening and fault leakage in relay zones. He found time to co-supervise alumna Salsabila Nazari’s undergraduate research into sand injectites crosscut by the fault veins. Jack has been both dating and doing preliminary analyses of the size of earthquakes recorded by pseudotachylyte in a low-angle normal fault. Alumnus Mike Schiltz continued to work on a related senior research project after graduating in Spring 2015. Hanna Bartram, co-supervised with Harold Tobin, is untangling a mess of metamorphic tectonites (once ocean floor) cut by calcite veins and anas-tomosing fault zones in the Rodeo Cove thrust zone, exposed in the Franciscan formation along the California coast. All part, as alumna Marcia Bjornerud (Professor, Lawrence Uni-versity) might say, of the autobiography of the Earth. [Check out Prof. Bjornerud’s New Yorker articles, including The Quiet Before the Quake here: http://www.newyorker.com/contributors/marcia-bjornerud].

ShAun mArcott The past year has been productive and packed full of things to keep our group busy. In Febru-ary, the final renovations were completed for the 4th floor cosmogenic lab and the group wasted no time getting into it to prepare our northern Greenland samples. Graduate students Melissa Reusché and Elizabeth Ceperley, along with undergraduates Alex Horvath and



Claire Vavrus spent the better part of the spring preparing and processing samples in the new lab and made heroic efforts to get our new operation off the ground. In the summer, Melissa accepted an internship at Hess Co. (and recently accepted a full-time posi-tion beginning next year) and Alex began transitioning to work on his second undergraduate project with Luke Zoet. Meanwhile, Elizabeth and Claire took up the charge over the summer to keep things moving along in lab, along with undergraduate, Hannah Zimmerman, who is working on an oceanography based project in collaboration with Ian Orland, John Valley, Clay Kelly, and myself. During the summer, Elizabeth also spent time at Lamont Dougherty Observa-tory to sample ocean sediment cores and was accepted to an intensive 15-day field school in Newfoundland. Starting this fall, our lab group will nearly double in size as two new postdocs join my group (Aaron Barth from Oregon State University and Jeremiah Marsicek from the University of Wyoming), and another graduate student (Cameron Batchelor from Appala-chian State University). Aaron joins my lab with an expertise in cosmogenic dating and will be working with me on an alpine glacial project in North and South America. Jeremiah is a native Wisconsinite and specializes in data analyses and geo-statistics, and is working with me on a large, collaborative project to investigate global Holocene climate changes. Cameron is working with Ian Orland, Museum Director Richard Slaughter, and myself on stalagmites from Cave of the Mounds in order to reconstruct permafrost histories in southern Wisconsin over the last several glacial cycles. Beyond the lab and office work here in Madison, I haven’t been able to get out for fieldwork this past year, which would explain the additional 5-10 lbs that seems to have amassed. Oh well, the upshot is that I was finally here for my anniversary (something I traditionally miss). Looking forward to the next year with my growing group and getting back into the field where a geologist belongs.

ShAnAn PeterSHello Geobadgers! Another year, and things have never been better. The Macrostrat group is bigger than ever and continues to make progress. I’m fortunate to still have Programmer

Analyst John Czaplewski leading the informat-ics and programmatic aspects of the Macrostrat database, and generally serving as a geosnatially-savvy technical consultant for many in the Dept. We’ve managed to put together a few tools that make geological data more accessible. Check out the geological maps component of Mac-rostrat, (https://macrostrat.org/burwell), or ex-plore for specific geological units in Sift (https://macrostrat.org/sift). Rockd (https://rockd.org), the mobile application you can use to log your field trips, will be out soon too! The data behind the Macrostrat scenes are being used by Post-doctoral Scholar Jon Husson to explore a wide range of topics in biogeochemical and sediment cycling. Senior Programmer Analyst Michael McClennen continues to improve access to the Paleobiology Database (https://paleobiodb.org), hosted here, and Andrew Zaffos is exploring those data and their relationship to paleogeog-raphy and Macrostrat. It has been a big year for students. Ben Linzmeier’s paper on SIMS analysis of Nautilus appeared in print and he pulled down a disser-tation completion fellowship from UW. Sharon McMullen returned from a summer internship at Hess with a job offer and is on a fast track to finish. Congrats Sharon! Second year M.S. stu-dent Ben Barnes snagged the Robert and Caro-lyn Maby Memorial Grant from the AAPG and the Alexander and Geraldine Wanek Award from GSA to pursue his work on carbonate cements in the Bakken Formation. He had a successful sampling campaign at the USGS core lab. The J. Valley lab group have been great collabora-tors on this work. Scott Hartman continues to be the student I encounter most frequently on

the internet. His illustrations of dinosaurs are everywhere! Erika Ito, undergraduate ’16 major, also has been active in the group, helping us to wrangle data for Macrostrat and GeoDeepDive (https://geodeepdive.org), the latter of which is being carried out with colleagues across the street in computer science.

eric e. rodenAll my adult life I’ve heard that the 20th century was the century of physics and chemistry, and that the 21st century will be the cen-tury of biology. It turns out that was true in ways I would never have imagined, particularly from the vantage point of an geomicro-

biologist interested in low-temperature biogeo-chemical cycling at or near the Earth’s surface. Although geobiologists have been working with living systems forever, recent advances in DNA sequencing and bioinformatics technologies are paving the way to rapid advances in our ability to unravel the connection between observable phenomena (e.g. microbially-driven geochemi-cal processes) and the unobservable genetic basis underlying those phenomena. With these new tools we can come to grips with the operation of modern systems in unprecedented detail, and also peer backward in time—through genomic analysis—to gain insight into the organ-isms and processes that may have dominated life on the early Earth. The Geomicrobiology Lab continues to embrace these new tools, with a specific interest in how microbial cells can gain energy by transferring electrons (i.e. metabolic energy equivalents) to and/or from solutes and mineral phases external to the cell membrane. Of foremost interest are dissimilatory iron-reducing microorganisms that transfer electrons to insoluble iron oxides and phyllosilicates during respiration; and chemolithotrophic iron-oxidizing that extract electrons from aqueous and mineral-bound Fe(II) sources. Over the past six months we produced our first two major publications whose centerpiece was a so-called “metagenomic” (broadly defined as the study of genetic material recovered directly from en-vironmental samples) analysis of the metabolic capacities of mixed microbial communities in-volved in the extracellular redox metabolism of Fe. Assistant Research Scientist Shaomei He’s paper in Applied and Environmental Microbiol-ogy provided long-awaited insight into how a

chemolithotrophic iron-oxidizing culture that we’ve worked with for almost 20 years can directly attack insoluble Fe(II)-bearing minerals. Meanwhile, Nathan Fortney (PhD student in the NASA sup-ported Wisconsin Astrobiology Re-search Consortium) published his M.S. thesis in Geobiology, which utilized metagenomic analysis to reveal novel pathways for micro-bial iron reduction in Chocolate Pots Hot Springs in Yellowstone National Park. Nathan’s analysis also provided evidence for the first known microbial taxa that is capable of both iron and sulfate reduction, which in turn has led to a collaboration with Penn State University to isolate the organism identified in his genomic libraries. The He et al. and Fortney et al. papers were highlighted in an April 5, 2016 UW-Madison press release (see photo). Two students in the campus-wide Environmental Chemistry and Technology (Jacqueline Meija and Noah Stern) are utilizing analogous approaches to understand mechanisms whereby organic carbon associated with iron oxides can fuel and accelerate iron reduction, which has important implications toward the lability and mobility of soil carbon. All of these studies seek to link experiment and observation with genomic analysis, which, one could say, has become part of the “sensibility” of geomicrobiologists all over the world. Though it comes in many flavors, this basic modus operandi will no doubt drive a continuous stream of new discoveries for many years to come.

BrAd SingerJanuary 2016 began in a flurry as I led, with Cliff Thurber, two weeks of operations at Laguna del Maule, Chile. The field crew of 20 people included Neal Lord, Crystal Wespestad, Basil Tikoff, and alumna Dana Peterson (now at Cornell). This involved a week of helicopter-supported work, including installation of 25 seismometers, digital photogrammetry over 400 km2, and deployment of field geology teams. PhD students Alan Schaen and Nico Garib-aldi were helicoptered in to the 6 Ma Risco Bayo-Huemul pluton for a week of mapping and sampling. So that we could prepare for the big 2016 deployment, in October, 2015 I had put on my Telemark skis and trekked into Laguna del

Maule to collect data from two of the seismom-eters intalled earlier that year. I presented a paper at the 2016 Goldschmidt Conference in Yokohama on triggering of the great 1912 Katmai-Novarupta, Alaska eruption by basaltic recharge that, based on fine-scale zoning recorded in plagioclase and orthopyroxene, took place only weeks prior to the eruption. The paper, now published in EPSL, is based on work I completed while on Sabbatical in 2015 at the Earth Observatory of Singapore with former PhD student—now tenured professor—Fidel Costa. Following the Goldschmidt Conference, I undertook field work to collect samples from rhyolitic ash beds in the famous Cretaceous strata of Hokkaido Japan. Fortunately, we did not encounter one of the island's infamous brown bears during this work. Then it was on to China, where, as a Distinguished Lecturer of the Chinese Academy of Sciences, I gave 6 talks on the Laguna del Maule project, and on advances made possible by Brian Jicha using our multi-collector mass spectrometer for 40Ar/39Ar dating in Beijing, Guangzhou, and Wuhan. In May PhD student Jack Hoehn, Laurel Goodwin, Brian Jicha and I began an exciting collabora-tion that capitalizes on the in situ sampling capabilities of a new ultraviolet laser in WiscAr lab to date pseudotachylyte (see cover story). In August it was on to Boise to co-convene the 2nd IsoAstro workshop with Steve Meyers and Mark Schmitz. This workshop brought together 45 students and researchers from 8 countries to explore integrating radioisotope dating and

astrochronology; by all accounts it was a great success. While all of these things were happening, I assumed the role of Science Editor of GSA Bulletin for a 4-year term, joining GeoBadger alum Aaron Cavosie, and David Scofield. Nathan Andersen and Paola Martinez continue blazing new trails in understanding Andean magmatism in their PhD disserta-tion and MS thesis projects, re-spectively. On September 8, 2016 Nathan's wife Emi gave birth to daughter Wynn Hikari Andersen—

congratulations! Another milestone: Teri and I, plus family, celebrated Zoe's graduation from the Univer-sity of Chicago in June—wow, did that really just happen!

cliFFord h. thurBerThis past year has been one of many highlights. In January 2016, working with a great field crew, we

installed 25 seismic stations around Laguna del Maule to complete the deployment of a seismic array that we started installing in January 2015. It took months of planning to make that deploy-ment a success. Grad student Crystal Wespes-tad was a force in the field, and she has begun analyzing the new data retrieved from the array for her thesis research. Undergrad Bethany Vanderhoof has also been participating in the initial data analysis. For a second field project, Neal Lord and our collaborators deployed about 40 instruments on Unalaska Island in summer 2015, as part of a project involving UW-Madison, UC-Riverside, and the Alaska Volcano Observatory. We have the dual goals of analyz-ing non-volcanic tremor within the subduction zone offshore and imaging the internal structure of Makushin volcano. The instruments were retrieved in summer 2016 and the data analysis will begin soon. In the "when it rains it pours" category, much of the year was spent designing and arranging the instrumentation for a dense seismic array for a project at the Brady geother-mal site in Nevada. 240 state-of-the-art nodal seismic instruments were deployed in March 2016 for a period of about 3 weeks. I trucked the nodes from Salt Lake City, where they had been programmed, to Fernley Nevada for the deployment, and then trucked them back to Salt Lake City for the data downloading. The field work was a great success. Post-doc Xiang-fang Zeng, grad student Lesley Parker, and

many others took part in various phases of the field work. 9 km of optical fiber for Distributed Acoustic Sensing was also deployed at Brady. Together, the data will allow for remarkably high-resolution imaging of the shallow part of the geothermal system. We also hope to be able to detect small temporal changes in the subsurface seismic velocity structure caused by changes in the water injection pumping rate. Grad student Bin Guo completed his MS thesis on the Alpine Fault, New Zealand, in summer 2015, and since then has been working mostly on the study of nonvolcanic tremor along the San Andreas Fault in the Parkfield region as one part of his PhD research. Grad student David Watkins finished his MS thesis on seismic to-mography of the subduction zone in the Jalisco region of Mexico in spring 2016, and now works for the USGS in Middleton. Assistant Scientist Ninfa Bennington has been incredibly busy this year, working on two projects in Alaska, including a seismic deployment plus magneto-telluric field work at Okmok volcano, analyzing ambient noise data from Laguna del Maule, and making preparations for magnetotelluric field work at Yellowstone in summer 2017. Together we recruited three new graduate students, Reagan Cronin, Laney Hart, and David (DJ) Miller to work with Ninfa on her projects start-ing in fall 2016.

BASil tikoFFThe structural geology group continues to do well and is very active. Charlotte Bate, Rich-ard Becker, Bridget Garnier, Nico Garib-aldi, Saurabh Ghanekar, Nick Roberts, and Maureen Kahn are all working on their degrees. There are two highlights associated with Zach Michels: First, he finished his PhD degree, focusing on developing a new type of microstructural analyses for deformed rocks. Second, he became a parent about two months later. Talk about a one-two combination! Post-doc Vasili Chatzaras left UW-Madison January 2016 to finish the third year of his Marie Curie fellowship at the University of Utrecht, Netherlands. This was the plan all along, but we still miss him. I have been working on two main projects in the last year. The first is a theme issue of the journal Lithosphere (published by the Geological Society of America) on the Earth-Scope Idaho-Oregon project. The UW-Madison component of the work was done by Nicole Braudy, Ad Byerly, and Tor Stetson-Lee, and was based on earlier work by alumnus Scott Giorgis. This special volume has been a

significant undertaking, and Maureen Kahn has been a major help in getting it submitted. The second main project is working on the Strabo digital data system, which is a digital database (and more) for Structural Geology and Tecton-ics. Doug Walker (Kansas) and Julie Newman (Texas A&M) are my main collaborators on this project, along with a whole crew of students and programmers. Randy Williams and Zach Michels have been instrumental in making it work from the UW-Madison side. Otherwise, there are a bunch of other ongoing projects that I enjoy working on, including Laguna de Maule (the large project lead by Brad Singer and involving Nico Garibaldi), geospatial statics (with alumna Sarah Titus, and involving Nick Roberts and others in the structural geology group), and ongoing work in Central America with Chuck DeMets (with students Bridget Garnier and Andria Ellis). Finally, with a Herculean effort from many in the structural geology students—and some mastereminding by Laurel Goodwin—I am back in an office in the Isolation Ward. Thank you to everyone for your efforts! It isn’t the prettiest office in the whole building (read: It is ugly), but it is nice to be home.

John w. VAlleyJake Cammack, Adam Denny and David McDougal (with Noriko Kita) completed MS theses last year on 3.4 Ga cherts in the Pilbara Craton that host the oldest accepted stromato-lites; carbonate diagenesis in the Illinois Basin; and chondritic meteorites, respectively. Adam is shifting his sights to the Bakken Fm for a PhD. The NOVA special, “Life’s Rocky Start” aired Jan. 13, 2016 and featured clips of Jake and me in the field in Western Australia and also Mike Spicuzza and Kouki Kitajima in the lab in Madison. It can be viewed free on line (search the title). Phil Gopon finished his PhD, super-vised with John Fournelle, developing novel techniques of microanalysis that he applied to samples from the Moon. New post-doctoral fellows, Huan Cui and Akizumi Ishida, joined the astrobiology group. Huan is studying the Great Oxidation Event (~2.3 Ga) by analysis of S isotopes in Huronian sediments from Ontario, well known to White Lakers. Aki is examining Precambrian organic matter for C and N isotope ratios as a test of biogenicity and metabolism, including the famous Gunflint microfossils col-lected by Stanley Tyler who in one publication (Tyler and Barghoorn 1954) tripled the time life was known on Earth from 540 to 1850 Ma.

Former Post-Docs, Ian Orland and Maciej Sli-winski, were promoted to Assistant Research Scientists. Maciej is continuing SIMS studies of carbonate diagenesis motivated by DOE’s inter-est in CO

2 sequestration. Ian has returned to the

WiscSIMS Lab after a prestigious two-year NSF post-doc at the Univ. of Minnesota and is PI of a new NSF grant, “Seasonal dynamics of the Indo-Asian Monsoon during deglaciations." Andrée and I toured Japan in June before the Goldschmidt Conference in Yokohama where I gave two keynote lectures. Highlights before the meeting include: the craft pottery village of Shigaraki, now an international art cen-ter; numerous potteries and museums of Kutani ware; everything in Kyoto; and the Snow and Ice Museum in Kaga. The S&I Museum features research by Ukichiro Nakaya the glaciologist who classified snowflakes in the 1930’s and first synthesized them in the lab. We were hosted by Nakaya’s daughter, Fujiko, but disappointed that another daughter, Saki Olsen, could not make the trip from the US. It was Saki who first told us about this gem of a museum in the 1990’s when she was on sabbatical (metamor-phic petrology) at UW.

herBert F. wAngI am serving in my second year as a rotator at NSF in the Instrumentation and Facilities program of the Earth Sciences Division. I have also participated in reviews and panels in the Geophysics, Sedimentary Geology & Paleon-tology, EarthCube, and Paleo Perspectives on Climate Change (P2C2) programs. The variety has given me different perspectives on Earth Science. NSF gives its rotators the opportunity to keep up with research through its Indepen-dent Research/Development (IR/D) program. In March I participated in the first week of the field portion of Kurt Feigl’s PoroTomo project at Brady Hot Springs. The Distributed Acoustic Sensing (DAS) experiment is an order of magni-tude larger in size than our earlier ones on Lake Mendota ice and at Garner Valley, CA. In August Chelsea Lancelle completed her PhD based on the Garner Valley data. She has started a lec-turer position at UW-Platteville. The other proj-ect that took place throughout the spring and summer was Lawrence Berkeley National Lab’s (LBNL) project called kISMET (I’ll let you google it). Bezalel Haimson, two of his former PhD students, Moo Lee (Sandia National Laborato-ries) and Tom Doe (Golder Associates) (Tom received a joint PhD with Geoscience), new GLE rock mechanics professor, Hiroki Sone, GLE



grad student Peter Vigilante, Neal Lord, and I were involved with obtaining a stress measure-ment by hydraulic fracturing at a depth of about 5000 feet in the former Homestake gold mine in Lead, South Dakota. Today the mine is called the Sanford Underground Research Facility (SURF) as a number of physics experiments are taking place at the 4850-foot depth level. Previously JoAnn Gage had conducted rock mechanics measurements at the 4100-foot depth level for her 2012 PhD thesis.

huiFAng XuGraduate students Yihang Fang and Shiyun Jin have finished their MS theses. Yihang moved to University of Hawaii, and Shiyun continues on his PhD study. Yihang’s thesis is about the correlation between dolomite and microbial biomass in ancient and modern car-bonate rocks with alternating dolomite/calcite lamination. Shiyun’s thesis is about incommen-surately modulated structures of labradorite feldspars and their petrological implications. Shiyun has solved the enigma of labradorite structure that has puzzled mineralogists for decades since it was first discovery in 1940.

The structure will be published in American Mineralogist as a centennial paper. Graduate Seungyeol Lee continues on understanding crystal structures and domain structures of ferric iron oxide /hydroxide nano-minerals. Seungyeol’s recent paper about a new FeOOH phase (proto-goethite, a precursor to goethite) and preferential adsorption of arsenate anions on proto-goethite surfaces was selected as a “Highlights & Breakthroughs” paper in Ameri-can Mineralogist. The results of his study may impact the field of environmental science as the approach will open new gateways to examine adsorption processes on surfaces com-posed of multiple previously unknown nano-size phases with different surface structures and adsorption properties. Graduate student Nick Levitt (co-advised by Clark Johnson) is using isotopes to study sediment records in order to infer environmental conditions and habitability of life. His recent work includes carbonate precipitation campaigns designed to delineate formation rate boundaries between equilibrium and kinetically controlled 13C-18O bonding as well as Mg and Fe isotope partition-

ing during incorporation into mineral lattices. These experiments help inform his field studies of Archean carbonate platforms which record very early development of life on earth. Gradu-ate student Franklin Hobbs (co-advised by Professor Izabela Szlufarska, Materials Science and Engineering) continues on thermodynam-ics and kinetics of Ca-Mg-ordering in dolomite at low temperature. In the past year, I worked on solving crystal structures of nano-minerals (that never grow big, such as ferrihydrite) and intermediate pla-gioclase feldspars (between An

25 and An

75). Our

nano-mineral studies resulted in discovery of a new Fe

2O

3 mineral, luogufengite (see page 30).

Our results from Z-contrast imaging and single crystal X-ray diffraction demonstrate phase transformation from disordered high albite structure to ordered modulated structure (e1) with density modulation in Na-rich intermediate plagioclase via a modulated structure (e2) with-out density modulation. New parameters like amplitudes of modulation waves in intermediate plagioclase will help us to quantify ordering state that is related to cooling history of its host rock. l

Professor Dana H. Geary retired from teach-ing at the end of the 2015-16 academic year, her 30th on the UW campus. Dana, as she is known to everyone, is an invertebrate paleontologist, specializing in the evolution of mollusks.

A native Californian, Dana attended UC Santa Barbara as an undergraduate, majoring in biology. She then trained in geology as an M.S. student at the University of Colorado, where she completed a thesis on the evolution of a bivalve, Pleuriocardia, from the Western Interior Basin, under the direction of Erle G. Kauffman (“Mr. Interior Cretaceous”). Dana moved to Harvard for her Ph.D., working with Stephen J. Gould.

The problem of measuring exact rates of morphological evolutionary change in the fossil record has a long pedigree. In the 1940s, the American paleontologist G.G. Simpson examined Tertiary horse fossils over spans of tens of millions of years; he documented size increase in teeth and bones and interpreted it as slow, gradual evolution. But was the change actually slow and continuous or did it fluctuate between quick bursts and periods of stasis, as

Gould proposed in the 1970s? And how did the rates of change seen in the fossil record fit into the NeoDarwinian synthesis of modern evolutionary theory? What was needed were detailed morphological data on a much shorter time scale, in a circumscribed setting of known paleoecology: this was the approach Dana took in her dissertation research and has contin-ued as a main theme throughout her career. Her many studies of the molluscan fauna of a

Neogene lake (in Europe’s Pannonian Basin) have demonstrated evolutionary trends and speciation events on a scale of fractions of a million years.

Dana has had a prolific teaching practice in the department at all levels of instruction. She taught the elementary non-major course, Evolution and Extinction, for her entire career, with great success and student acclaim. For geology majors, she initiated the Paleobiology course, which brought in Zoology majors and grad students as well, and she took over In-vertebrate Paleo when Professor Clark retired. For several iterations, she and Professor Byers collaborated on the graduate Paleoecology class. Dana’s graduate students have worked on phases of the Pannonian project, as well

as on the Interior Cretaceous, Cenozoic strata in the Caribbean, and on the local Wisconsin Ordovician.

In recent years, Dana was involved at the campus level to organize the annual Darwin Day teach-in, where instruction and demonstra-tion about evolution are offered to students, faculty, researchers, non-scientists, laypersons, and children.

In retirement, Dana is returning to Boulder, the home of the Geological Society and where her geological career began. l

The contributions of glaciers to sea-level rise depend mainly on the speed at which ice is transported to the ocean. Fast moving glaciers advance primarily by slipping over their bases, as ice both rides a deforming bed of sediment and/or slides over the bed. Subglacial erosion, deposition and landform development are also significantly influenced by glacial slip. Although subglacial processes are a vital aspect of both glacial geology and glaciology, they are not well understood and remain a key uncertainty in our knowledge of glaciers. My research primarily focuses on understanding glacier motion through a combination of field observation, laboratory experiments, and theoretical analysis. The focus of our group’s work sits at the intersection of glaciology and glacial geology as we use techniques and tools from both disciplines to explore glacier processes.

Glacial Field Observations:We conduct field work on active glaciers, and in doing so we largely use geophysical techniques to understand the mechanisms by which they deform, slide, erode and deposit. These techniques include ground penetrating radar (GPR), passive seismic readings, global positioning systems (GPS), and satellite observations that help us develop an understanding of the hidden processes at work below the glacier. We have used these techniques in Iceland to study an active drumlin field below the ice led by graduate student Jacob Woodard (Fig 1), in Antarctica to observe glacial seismicity that was modulated by daily ocean tides, and in Greenland to observe glacial seismicity led by graduate student Ian McBrearty. In the past I have also worked in the Svartisen subglacial laboratory, which is a truly unique facility that consists of a ca. 1 km tunnel bored under a glacier in Norway that lets us access the base of the actual active glacier (Fig 2). From the base of the glacier, instruments such as seismometers and custom drag plates can be deployed and basal ice samples can be collected to measure how

the ice slips over its base. Many of the glacial landforms located in Wisconsin such as drumlins, eskers, till plains, tunnel channels and moraines offer a record of past glaciers. The fact that these landforms are abundantly available, accessible, and local makes the State of Wisconsin a great natural laboratory for glacier studies. Studying these deposits provides valuable insight into kinematics and dynamics of paleo glaciers, in turn helping us understand active glaciers. To investigate these landforms, we have used GPR coupled with litho-stratigraphic analysis to look into exposed drumlins in Iceland (Fig 3) and WI. We have also used LiDAR to map the Wisconsin drumlin field to a higher precision than previously possible, a project led by Nolan Barrette, an undergraduate Geoscience major. We plan to investigate the spacing and arrangement of the drumlins to better understand how the Green Bay Lobe (GBL) formed drumlins. Also, in collaboration with Elmo Rawling of the Wisconsin Geological and Natural History Survey, we have begun a project using active seismic, passive seismic, and GPR to investigate the large tunnel channels on the western margin of the Green Bay Lobe. These geologic remnants of large subglacial drainage events can act as an analog to the drainage events that take place under Antarctica and Greenland. Modern day glaciers provide insight into subglacial processes as they occur, but we are only capable of observing their behavior over a relatively small area and short period of time. Glacial deposits capture the results of various processes that occurred throughout long time periods, but lack the clarity afforded by observing active glaciers. Through the combination of modern glacier observation and glacial deposit analysis we are able to expand both the spatial and temporal scale of our glacier process observations.

Slip–Sliding Away


based on field work. Experimental laboratories are labs in which set procedures have not been developed and each experiment and the instrumentation is designed from the ground up. At UW-Madison, we are building an experimental glacial lab. Currently, a large walk-in freezer (Fig 4) is near completion that will house several different rigs for the sole purpose of testing and developing the constituent equations of subglacial processes and ice deformation. We plan to run the first set of experiments in the Fall of 2016, which will test how ice that includes debris deforms. This project is led by Alex Horvath, a Materials Science Undergraduate. In addition, we are planning construction of a large ring-shear apparatus that is capable of constraining the mechanics of stable glacier slip. A ring shear spins a large ring of ice over a stationary bed and measures the resistance of the ice to sliding. Currently only one ring shear exists that is capable of experimentally studying glacier slip, but we hope to soon have similar capabilities at UW-Madison with modifications that will allow us to

probe a different set of glacier slip questions. One of our lab’s main strengths will be the precision temperature control of the samples. We will be able to regulate the temperature of our ice to within 0.01 C. With this level of control, we will be able to keep our experiments near 0 C for months on end, which is necessary for simulating process at the base of fast-moving glaciers. Through combining experimental work with field work we hope to better understand subglacial processes. Ultimately, a better understanding of subglacial processes will lead to an ability to improve glacier flow models. Exciting times lie ahead for the ice group at UW-Madison. We are making great strides and having a great time along the way. l

Laboratory and Theoretical WorkIn the field, things can be confusing. I’m sure most geologists have experienced this. There are so many processes at work simultaneously that it can be difficult to isolate the cause and effect of an observation. Because of the complicated nature of field data, our group often couples field observations with laboratory experiments, which can be better constrained, to explore the impacts of one process at a time. Bringing complicated systems into the lab and breaking them down to their basic features allows us to test one variable at a time and to use those findings to validate or invalidate the theoretical underpinnings of the field. Many scientists are drawn to the pursuit of glaciology and glacial geology because of the field work, and rightfully so! Glaciers produce some of the most beautiful terrain we encounter. However, there is nearly a complete lack of experimental laboratories to help substantiate what we observe and theorize

Iron oxides have served mankind for centuries as painting materials and navigation devices. There are five known crystalline polymorphs of Fe

2O

3 to date: hematite (α-Fe

2O

3), ma-

ghemite (γ-Fe2O

3), luogufengite (ε-Fe

2O

3),

β-Fe2O

3 (synthetic), and ζ-Fe

2O

3 (synthetic).

Luogufengite, ε-Fe2O

3, is a new Fe2O3

polymorph discovered in late Pleistocene basaltic scoria from the Menan Volcanic Complex nearby Rexburg, Idaho (Fig. 1). It is an oxidation product of Fe-bearing basaltic glass at high temperature and is associated with maghemite and hematite. Luogufengite is a dark brown nano-mineral—an intermediate polymorph between maghemite and hematite. Synthetic luogufengite was also discovered in ancient Chinese black-glazed Jian wares. New experimental results from annealing nontronite at high temperatures indicate that the stability of luogufengite in an amorphous silica matrix is size-dependent (Fig. 2). The difference among hematite, maghemite and luogufengite is the packing of oxygen atoms. The difference in oxygen packings results in dramatic changes in their magnetic properties. Non- magnetic he-matite has hexagonal closest packing (AB, 2-lay-er repeating), soft magnetism maghemite has cubic closest packing (ABC, 3-layer repeating), and hard magnetism (i.e., with large magnetic coercivity) luogufengite has doubled hexagonal packing (ABAC, 4-layer repeating, more like a mixed hexagonal and cubic packing).

Luogufengite is an important mineral that

records paleomagnetism of volcanic rocks because of its large magnetic coercivity. This unique magnetic property may explain the observed unusually high remanent magnetiza-tion in some igneous and metamorphic rocks and even Martian rocks. Some intergrowths of magnetite with ilmenite exsolution lamellae or hematite with magnetite lamellar precipitates have luogufengite-like 2-D crystalline charac-teristics with the doubled hexagonal packing at the interface between cubic and hexagonal structures. Luogufengite-like nano-domains at the magnetite / hematite interface might be responsible for the large coer-cive field of lodestones (natural magnets) that are partially oxidized magnetite with maghemite and hematite micro- and nano-precip-itates.

The mineral was named after the Chinese mineralogist, Professor Luo Gufeng (罗谷风, 1933- ), who has passionately taught crystallography and mineralogy at Nanjing University of China for more than 50 years. His textbook of “Introduction to Crystallogra-phy” (3 editions) is widely used in colleges and universities in China. Prof. Luo was co-organizer of S.W. “Bull” Bailey’s Short Course in Clay Mineralogy at Nanjing Univer-sity in 1985 (see Outcrop for 2014/15, p 12). He wrote the summary of the short course and reported in “Letters of Mineralogy, Petrology

Talk About a High-Pressure Work Environment…New Shocked Zircon Discoveries at Meteor Crater, Arizona, and Wisconsin’s

Own Rock Elm Impact Structure

Aaron J. Cavosie*

Few professional settings are free of occasional high-stress moments. For folks interested in planetary science and impact cratering, high-pressures caused by meteorite impact are where the action is. Shock waves generated when asteroids impact the Earth cause microscopic deformation microstructures in minerals such as zircon. Recent investigations of shocked zircon using electron backscatter diffraction on samples from the iconic Meteor Crater impact structure in Arizona, and from the Rock Elm impact structure in Wisconsin, have used mineral orientation data to reveal fundamental new insights into impact conditions. Rock Elm is a ~6 km diameter crater near Eau Claire that formed about 450 million years ago. The deeply eroded structure exposes shocked Cambrian Mt. Simon sandstone in the central uplifted area. In 2015, we discov-ered reidite, the ultra-rare high-pressure ZrSiO

4

polymorph of zircon, in a sample of brecciated sandstone from the central uplift. Overnight Rock Elm became only the fourth crater on Earth where reidite has been reported, and remains the only known occurrence of rei-dite in a sandstone target rock; its presence required an increase of pressure estimates for exposed rocks. Moving to the desert southwest, Meteor Crater is a 1.2 km diam-eter crater that formed in northern Arizona about 49 thousand years ago. The impact shocked Permian Coconino sandstone, causing it to locally melt and vaporize, leaving behind pumice-like blocks of highly vesicular, white, melted-silica glass. In 2016, we studied a sample of the shock-melted sandstone, and found that the zircon grains, formerly detrital, underwent a series of transformations, including twinning and conversion to reidite, before recrystallizing into sub-micrometer ‘bee-bees’ of newly formed ‘granu-lar’ zircon surrounded by SiO

2 glass. Granular zircon provides the

only record of the extreme conditions, including pressures in excess of 300,000 atmospheres and temperatures over 2000 °C, created on Earth’s surface by the impact event. Understanding the cryptic response of zircon to shock events is needed to interpret complicated zircon from other environments, such as the Moon, Mars, meteorites,

and Hadean grains from the early Earth. Impacts influenced how soon habitable conditions were established on the young Earth, so identi-fication of early shocked zircon has astrobiology applications, as they can be used to constrain models for the origin of life. l

mAry AnderSonIn March, I went to Shenzhen, China, to chair the first meeting of the advisory board for the new School of Environmental Science and Engineering at SUSTech (Southern University of Science and Technology). I and the other four board members were guests of Dean Chunmiao Zheng, one of our own hydrobadgers, who is charged with establishing a powerhouse for edu-cation and research in environmental science and engineering at SUSTech. We had a lively, informative and productive one-day board meet-ing. During the rest of my week-long visit I had a chance to tour the campus, meet the faculty and students and also see the impressive new city of Shenzhen as well as the nearby city of Guang-zhou. It was a memorable trip! Even after a respite of one year, I am still recovering from the ordeal of revising “Ap-plied Groundwater Modeling” for a 2nd edition (finally published by Elsevier in August 2015, with co-authors Bill Woessner and Randy Hunt). But I did manage one professional conference (the annual National Academy of Engineering meeting) in October in Washington, D.C. During another trip to Washington, D.C., Charles and I reconnected with Herb Wang (who is on leave doing a rotation with NSF) and his wife Rose-mary for a delightful dinner at a local restaurant.

Charles and I are still trying to travel as much as we can, often working in some opera (includ-ing in New York City, Toronto, San Francisco, and Washington, D.C.) and theater (the Shake-speare Festival in Stratford, Ontario). We are also enjoying local music and theater events and our vacation house in Door County.

dAVid l. clArkFirst, many thanks to those who contacted me, made contributions to the Arthritis Founda-tion, and showed other kinds of thoughtfulness following the death of Louise in April. After 65 years of marriage, life is different, but I am fortu-nate to interact daily with family and friends and hope to be continually involved with projects which will be interesting and useful.

In May, our small research group, Ray Ething-ton (U. Missouri), Scott Ritter, Bart Kowallis (BYU) and I, published the results of a two year Ordovician project in Palaios (Conodont biostra-tigraphy of the Ordovician Opohonga Limestone in west-central Utah, v. 31, p. 221-230) and when/if the weather cools, Scott and I hope to expand on this study, perhaps early this fall.

Finally, although I distributed most of my personal library before leaving Madison in

1999, I am now interested in transferring the remainder to anyone who has a good use for it. This includes a very long run of the Journal of Paleontology as well as Paleoceanography, and the Treatise on Invertebrate Paleontology. Also, I have approximately 90 interesting and significant theses and dissertations which I am reluctant to say good-bye to but which might be useful in some archival collection or library. Any suggestions? All inquiries will be considered! [email protected]

roBert h. dott, Jr.It hardly seems possible that I retired from teaching 21 years ago. No wonder I am so amazed at the many advances in our science since then. These are exciting times in the Geosciences with so many important new fossil discoveries and new findings from the ocean basins to the earth’s core to say nothing of those from outer space. I still enjoy visiting the department occasion-ally to hear visiting speakers and swap a few lies with colleagues. It was especially satisfying to be able to introduce my former student Professor Joanne Bourgeois (University of Washington- that other UW) at the annual geo-banquet to receive the Distinguished Alumna Award. While I regard the Department’s current faculty and graduate students to be top notch, I am very distressed by the cutbacks in financial support of the University by the current state government. Severe reductions in teaching assistantships have impacted the introductory courses so that, for example, no field trip can be offered in Geology 100. All across the campus faculty members are forced to do more with less and with essentially static salaries for several years. I still lead occasional little field trips and give talks for lay groups. My most important professional activity this year, however, was the completion finally of a large manuscript co-authored with my friend Ian W. D. Dalziel, formerly a faculty colleague in our Department but now at the University of Texas. Our manu-script is titled Charles Darwin The Geologist in Southern South America. When Darwin sailed around the world in the HMS Beagle (1831-1836), he was more a geologist than biologist. In our researches in southern South America Ian and I have followed Darwin’s footsteps and have seen the geology that he saw so we decided to write this paper to compare what he reported and interpreted with what we know today for Tierra del Fuego and Patagonia. Darwin emerges

as a very astute observer and collector of speci-mens. Needless to say, many of his interpretations have not stood the tests of time. For example he endorsed Charles Lyell’s ingenious floating iceberg hypothesis to explain erratic boulders. Especially important was his documentation of evidence of the uplift of both the Atlantic and Pacific coasts of Argentina and Chile indicated by raised, stair-stepped marine terraces. He explained these as by-products of the raising of the entire continent with the greatest uplift being along the Andes Mountains, which “float on a lake of molten stone double the size of the Black Sea.” He inferred a subterranean communication of magma with some occasionally breaking through the crust along great fissures parallel to the ranges. He also discussed the effects of a severe earthquake at Concepcion, Chile in 1835, which he linked with volcanic eruptions in the Andes. He was always thinking in large-scale terms and seeking unifying explanations. Our paper will be published in Earth Sciences History sometime in the next several months.

dAVe mickelSonAnother year older, but perhaps not wiser! No big trips for Vin and I this year, but I did spend a week in Massachusetts, where I attended my 50th Clark University reunion. Vin spent time in Knoxville being entertained by two of our grand-children (1 and 3 years old) when their parents were at work. I expect we will do another New England trip this fall. I co-authored and then self-published a book in April on the history of the neighbor-hood where my cousin and I grew up. Self-publishing was an interesting process—cheaper and faster than I had imagined! Google "From Raccoon Plain to Pakachoag Hill" to see a sum-mary. The Wisconsin Geological and Natural History Survey has posted the attempt by John Attig and I to summarize Wisconsin glacial advances and retreats in a map series (http://wgnhs.uwex.edu/pubs/es056/). I also have kept busy with a bluff erosion project and limited consulting. This is driven by higher lake levels. Lake Michigan has not been this high since 1997 and the base of the bluffs is now being eroded by waves in many places! If water level stays up, there will be houses in danger a few years from now! I have enjoyed doing a seminar and field trip with the new Quat generation of faculty, Luke Zoet and Shaun Marcott, and their students! Congratulations to former Quats Bill Mode and Bill Simpkins on their prestigious awards—see the awards page for more details! l

Emeritus Faculty News —2015-15


Phil Brown

The 50th year of the award winning Wasatch-Uinta Field Camp was marked with two gather-ings and celebrations. The first took place im-mediately following the conclusion of camp on July 24-27 in the iconic Chateau Apres in Park City. Nearly 30 past students and present and past faculty and TAs shared memories and stories from their years in Park City. Faculty from current consor-tium members (Illinois, Duluth, Michigan State, UW) as well as previous members (Iowa and Minnesota-Twin Cities) were present represent-ing 45 of the 50 years starting with Jim Grant (UMD) who taught 15 years including the first year, 1967. The faculty included five of the 10 present and past camp Directors. The all-important teaching assistants were repre-sented by individuals from MSU, Iowa and UW. Students from all six schools that have provided most of the nearly 2900 (60/y) campers were present.

Monday July 25th was set aside for planned field trips. A trip to the Bingham copper mine (now owned by Rio Tinto) was organized by Laura Nuno (Iowa ‘09). The second trip addressed the Late Pleistocene glacia-tion of the Wasatch and its connections to pluvial Lake Bonneville by Univ. of Utah geologists Brendon Quirk and Jeff Moore (Thanks!!). The third trip was designed to look at two geobiological targets on Antelope Island in the Great Salt Lake. As some-

times happens with plans—we are at the mercy of the Earth—the last week of July this year saw ~50% of the island subjected to wildfires. In particular the well exposed late Proterozoic snowball earth deposits of glacial diamictites and cap carbonates were inaccessible due to

the firefighting efforts. Despite this setback Russell Shapiro (Cal State Chico) provided the participants with a full day of interesting science. Sit-down, on camera interviews were done with willing participants and will be avail-able in the (hopefully) near future after edit-

ing. Tuesday the 26th was a free day and most of the attendees took the opportu-nity to visit Albion Basin which was in full bloom. Tuesday night we had a catered ban-quet at the Chateau that included all the registered attendees, significant others and children in addition to Ed and Sue Hosenfeld (the only owners the Chateau has ever had). We even convinced one of the ranchers whose land we invade every year to come to the event. Gordon

Medaris and Phil Brown represented the UW faculty. Laura Strickland (’94, TA ’97) and Allie

Macho (’11, TA ’13-’16) were the UW TAs present. Other past UW students included Scot Moss (’84), Angeline Catena (’09), Sydney Wallner (’11), Kyle Erdmann (’14) and Tom Vogel (MSU; UW M.S. ’61, PhD ‘63).

The second event was the five-school (Iowa, Illinois, Mich. State, Duluth, UW) group alumni gathering and Field Camp celebration that took place in Denver at GSA September 26.

Professor Emeritus David L. Clark

I was reading the L&S Annual Review for 2015-16 and the article concerning the Geology Museum (p 44-45). The fact that the museum has acquired an endowment is mar-velous. (See editor's note.) When I was Chair, there was always some tension over funds for the museum. It took effort by many people, including Bob Dott and myself, to preserve the museum during and after the Science Hall days. As I read the L&S article, it reminded me of the Museum's pre-Klaus days and how the present Museum really got started.

In the 1960’s, many of us were concerned that the Museum was on the verge of falling into oblivion. By 1970, the Museum consisted of several old display cases, plaster casts and the mastodon in that large second floor room outside the offices of Lewis Cline and Lowell Laudon in Science Hall. I contacted Assistant Dean Bob Doremus and asked him for some minor funding to fix it up. The idea was that instead of several old display cases in a big room, that with a little effort and funds we could put up a few partitions and wall exhibits that would include an entrance and an exit and a brief story so that folks wouldn't just wander around the old cases, but would be guided through an ordered sequence of minerals, rocks and fossils that would tell part of the story of geology. Although some were critical of spending any money on Science Hall when a new building was in the hoped-for future, my idea was that all of the partitions and new wall displays could be transferred to the new building and what at least a few of us hoped would be a new Museum.

Doremus approved the up-grade of the Museum. I was Chair in 1971 and requested a full-time curator to take charge of the autho-rized Science Hall remodeling as well as help plan the Museum in the new building, which by that time was looking real. I argued that it was foolish to spend even a little money on

the physical aspects of a Museum if there was not a full-time curator. Doremus agreed and got authorization from Dean Kleene to hire a full-time curator.

My Fulbright experience in Germany a few years earlier (1965-66) exposed me to the fact that most of the European departments had full-time, non-teaching curators. Thinking that Europe would be a good place to look, I con-tacted our friend Dolf Seilacher at Tubingen and asked if he could suggest someone for the new position. As it turned out, the curator at Tubingen at that time was Frank Westphal, who had a brother, Klaus Westphal, who had just finished his PhD. Klaus was interested and the rest, as they say, is history. Klaus was hired, took care of the revised Science Hall Museum until Weeks Hall was functional, and then helped plan and supervise the new Museum, which took a while to get going, but today is flourishing and even has its own endowment! It was a good decision to hang

A Brief History of the Museum

in there and see the Science Hall project through because ultimately it justified the development of the present Museum.

Since Klaus retired, Richard Slaughter has expanded the program substantially in staff, displays, collection and outreach. The Friends of the Geology Museum, begun by Klaus, has grown to be an important, supporting arm helping to make our museum such a great asset to University outreach. For example, every spring and fall dozens of yellow buses converge upon Weeks Hall bringing thou-sands of young school children to learn about the wonders of geology. l

Editor’s note: Dave and Sherry Lesar launched the museum's endowment with a $2 million gift, which was matched with $1.5 million from John and Tashia Morgridge. The tremendous generosity of these donors is deeply appreciated and inspiring.

Shedding Light in Dark PlacesCave of the Mounds (located near Mt. Horeb in southwestern Wisconsin) has been a geo-tourism destination for 75 years and has partnered with the museum on educational and research endeavors in the past. This year Ian Orland and Rich Slaughter joined forces to collect, prepare and date speleothems from this National Historic Landmark. Their research is creating the premier paleoclimate record for Wisconsin and has spawned a project for incoming graduate student Cameron Batchelor. Many thanks to Brian Hess for his help cutting and polishing these priceless specimens.

Diverse and Dazzling AdditionsOur collection continues to grow with the addition of interesting and unique pieces. At the Tucson Gem and Mineral Show in February, the Friends of the Geology Museum purchased a stunning specimen—a conglomerate made from the tusks and teeth from the semi-aquatic mammal, Desmostylus. We’ve begun receiving parts of a significant mineral donation from Tom Hudak. The highlights so far include a nine pound cluster of stibnite crystals and an

unusual sulfur stalagmite. Jerry Gunder-son continues to bestow wonderful fossils upon our collection—this year he donated Ordovician eurypterids with preserved cuticle. Most recently, a collection of enigmatic fossils entombed in Hixton Silicified Sandstone was given to the museum by Robert “Ernie” Boszhardt along with some large knapped pieces of the same stone. This orthoquartzite was prized by Paleo Indians for making knives and hide scrap-ers since it stayed sharper longer than other materials.

On the RoadWhile we are getting record traffic through the museum doors, we recognize that many people can’t make it here. In a concerted effort to take specimens and speakers on the road. We have traveled to a variety of venues from the local YWCA to nursing homes, gem and mineral shows to Madison’s Nerd Night. A special highlight, 2016 marked our tenth year of providing program-ming at Pope Farm Park in Middleton. In our tenure there we’ve talked to over 3,000 fourth graders about Dane County’s Ice Age past. Special thanks to Dave and Ruth Divine, Amy Cheng and Charles Sword for their financial support in these outreach activities. l

Museum personnel spend multiple days each spring cultivating curiosity at Pope Farm Park. Each fourth grade class in the Middleton-Cross Plains School District makes a year-end trip to learn about Wisconsin’s rich history during an all-day, outdoor field experience.

Howdy pardners! The museum crew (Scott Hartman, Dave Lovelace, Mel Reusche, Rich Slaughter, Tuan Syazana Tuan Ab Rashid, Brooke Norsted, Carrie Eaton, Lee Bongey) put on their best duds for this year’s Western-themed Behind the Scenes Night.
