February, 2017 Background to the proposal to add names at Newberry Volcano By Julie Donnelly-Nolan, Research Geologist, USGS Menlo Park CA Newberry Volcano is one of the most hazardous volcanoes in the continental United States. Its lavas cover about 1200 square miles and underlie populated areas including Sunriver and downtown Bend OR. The lava flow that underlies downtown Bend and formed Lava River Cave erupted from vents midway up the north flank of the volcano and reached the south edge of Redmond. Another of several far-traveled flows reached Smith Rock and temporarily filled the Crooked River channel. On the main edifice of Newberry, there are as many as 400 cinder cones that represent >250 eruptions during the half-million-year history of the volcano. Most of these involve cinder cone(s) and lava flows that traveled a few miles to a dozen miles. Several explosive caldera collapse eruptions have also occurred, accompanied by pyroclastic flows and by ash falls, some of which reached the Bay Area. In an effort to understand the history of the volcano and evaluate its potential hazards, the USGS has had a long-term project at Newberry to decipher how it has behaved through time. In addition to geologic mapping, USGS scientists do argon dating of lava flows, assess episodic behavior via paleomagnetism, study the volcanic ash deposits, and sample geothermal drill cores. The goal is to understand how the volcano is likely to behave if it should become restless. The geologic map incorporates much of this information and is the fundamental document that tells the story of the volcano. It will form the basis of a new volcano hazards assessment. A geologic map names the various mapped units (e.g., “the basalt of Klone Butte”), but Newberry is the land of many cones and few names. Some lava flows have multiple names, while some areas with many lava flows have almost no names. I worked with long-time USGS volunteer and retired DNF geologist Bob Jensen to propose additional names on the volcano. We contacted a wide variety of agencies and people including the regional FS office and took our draft proposal to a meeting of the Oregon Geographic Names Board (OGNB) in 2008. The proposal was subsequently presented to the DNF district ranger. A draft final version of the map was compiled in 2010. But the advent of high quality lidar coverage beginning in 2011 changed the timeline for the mapping. Many new features became visible, especially in heavily forested and difficult-to-reach parts of the volcano. That work is now largely complete and a final compilation of the map is underway. At the urging of the OGNB, we have dusted off and modified our original naming proposal in an effort to add names in critical areas. The proposal also includes names used previously in an informal way in various geologic publications. We began using many of these names for orienting ourselves in everyday work and we chose them based on shape, animal or tree name, history, etc. Each name in the spreadsheet has an explanation and description of the feature. We have identified and named the specific features that provide the most benefit to the geologic map, but the names we suggest need not be the final names.

Newberry Volcano Geologic Map Feature Names –
NEW R6 Geographic Name Proposal
Background: R6 Geographic Names Advisors for the USDA Forest Service to the Oregon
Geographic Names Board (OGNB) and the Washington Committee on Geographic Names (WCGN),
Maxine Kline and Jesse Nett, received notification of an incoming proposal to the OGNB to name
several features upon the Newberry Volcano edifice.
The proposal will be submitted to the OGNB by Dr. Julie Donnelly-Nolan, Geologist, USGS Volcano
Hazards Team, Menlo Park, CA, and Robert Jensen, retired Deschutes National Forest Geologist.
The team has researched Newberry Volcano for several years. Over two hundred geographic
features upon the edifice are currently unnamed. The proposal intends to provide geographic
reference for an upcoming USGS-produced geological map.
Impact: The OGNB will notify board members, tribal interests, county governments, and historical societies to investigate and request comments regarding the proposed geographic names. Once all input is received, the OGNB will vote to accept or not accept the proposal for the U.S. Board of Geographic Names. If the OGNB votes to accept the proposal, they will ask the Forest to provide a written concurrence or non-concurrence, accompanied by a brief narrative justifying the decision. Since the features are located on USDA Forest Service-administered lands (Deschutes National Forest – not designated Forest Service wilderness), the thorough review of the proposal details will incur a time impact. The feedback from the Forest will be forwarded to Betsy Kanalley, the Geospatial Products and Services Program Manager at the Washington Office, who will work with the Chief’s office for an official Agency response. Current Situation: The scope of this briefing is to notify the leadership of Deschutes National Forest of the
upcoming proposal of approximately 95 features upon the Newberry Volcano edifice while also familiarizing the
staff with the new R6 Geographic Names process.
Recommendations for the impacted Forest leadership and staff:
-Review briefing and Appendices A - D.
-Refer to the BGN Principles, Policies, and Procedures for Domestic
Geographic Names. http://geonames.usgs.gov/domestic/policies.htm

Proposed Formal Names on Newberry Volcano
1. Proposed Names on north flank
1A. Proposed names with previous use (17) Astronaut Butte
Name (History): From 1964 to 1968, NASA astronauts and scientists visited central Oregon many times for training and testing of equipment related to the Lunar landing program. Great view to south from top of this cinder cone, and thus an appropriate choice for the "astronaut" name. Previous Use of Name: The Pacific Northwest Seismic Network has a seismic station on the butte and calls it Astronaut Butte (https://www.pnsn.org/seismogram/current/asbu) Background: A cinder cone a half mile in diameter and 500 feet high with a summit elevation of 5094 feet. It is the source of lava flow that reaches Hwy. 97 just south of Vandevert Road. Feature Class: Summit Elevation: 5094 feet (summit) County: Deschutes Topographic Quadrangle: Lava Cast Forest Location: This cone is located about 2/3 mile SW of Sugar Pine Butte. Located in: T. 20 S., R. 11 E., Sec. 23, 24 Map Location: N 43° 49’ 22.0” W 121° 21’ 58.7” N 43.82279° W 121.36630°
Camp Abbot Buttes
Name (History): World War II Camp Abbot was at site of Sunriver. Previous Use of Name: There is a large quarry, that has been called the Camp Abbot Cinder Pit by the Deschutes National Forest since at least 1980, in one of the cinder cones along the chain. Background: This two-mile-long chain of cones contains about a dozen vents.

Name (Location): Eruptive activity along this zone extends from Lava Butte south to the East Lake Fissure. Previous Use of Name: Name used by Peterson and Groh (1965). Also in MacLeod and others (1995). The name was used informally in Mckay and others (2009) and by Robinson and others (2015) on USGS SIM 3329 featuring the volcano’s youngest lava flows, but the rift zone is an important feature that includes lava flows that have commonly used names dating to geologic work in the 1960’s and 1980’s. Background: The northwest rift zone erupted lavas about 7,000 years ago subsequent to the catastrophic eruption that formed Crater Lake and blanketed much of central and eastern Oregon with volcanic ash. The northernmost of these eruptions took place at Lava Butte; its lavas flowed northwest and blocked the Deschutes River for a time. Additional vents and flows (including the lava flow that hosts Lava Cast Forest) are present nearly continuously uphill to the southeast, cross the north rim of Newberry caldera and form the East Lake Fissure. Additional vents broke open on the upper southwest side of the volcano and produced the Surveyors Lava Flow.

2A. Proposed Names related to drainage system on west flank (6)
14 of 36
The west flank of Newberry Volcano was eroded by glacial meltwaters following the caldera forming eruption about 75,000 years ago. This erosion created seven primary channels. Today the only active channel is Paulina Creek. The other channels were first studied by Donnelly-Nolan and Jensen (2009) and were given informal names at that time. From north to south the proposed channel names are: Stearns Draw
Name (Location): The mouth of the draw is east of the Stearns railroad siding. Previous Use of Name: Name used by Donnelly-Nolan and Jensen (2009). Background: This 5-mile long draw is one of the major dry channels on the northwest side of Newberry Volcano. Now dry, it has been occupied multiple times by floodwaters, probably related to melting ice on the upper parts of the volcano. It is lined by terraces of coarse cobble gravels, partially filled by younger lava flows, and dissected by later floods that have deposited sand and finer gravel that extends west across Hwy 97. The mouth of the draw is located at an elevation of 4215 feet (T. 21 S., R. 11 E., Sec. 7), just east of the Stearns railroad siding. The draw extends about 5 miles to the east with the upper end of the draw in cut into caldera filling ash flow deposits, at an elevation of 4720 feet (T. 21 S., R. 11 E., Sec. 13).

Footbridge Falls
Name (Location): A footbridge crosses creek just above this location. The locality is easily accessed and commonly visited. Previous Use of Name: Commonly used local name. Background: A major waterfall along Paulina Creek. Lava flow from a vent destroyed by caldera formation forms the step in topography that has resulted in this waterfall. Paulina Creek is undersized for the features found along the channel; its average annual discharge is 18 cubic feet per second. Between 2000 and 4000 years ago a small waterfall eroded into the caldera-forming tuff further eroded the tuff to reach Paulina Lake and dropped the lake’s level by about 8 feet. This resulted in a flood with an estimated discharge rate of about 7000 cubic feet per second (almost 400 times the annual rate). The flood lasted no more than two days.

4. Proposed Names on east flank
4A. Proposed Names related to drainage system on east flank (8) The east flank of Newberry Volcano has a longer and more complex erosional history than the west flank. More than a dozen major channels exists, that were first studied by Donnelly-Nolan and Jensen (2009) and were given informal names at that time. From north to south the proposed channel names are: Junction Draw
Name (Location): This draw is crossed by Rd. 18 between the junctions of Rd. 18 & 1825 and Rd. 18 & 2015 (Horse Ridge Quad., Sec. 36, T. 19 S., R. 13 E.) and is crossed by Rd. 18 on a large former railroad fill. Previous Use of Name: Name used by Donnelly-Nolan and Jensen (2009). Background: This 21-mile long drainage extends from near the north rim of Newberry Caldera to north of Horse Ridge to join Dry River. The lowest definable channel is at an elevation of 4200 feet (T. 19. S., R. 14 E., Sec. 18) where the channel disappears beneath the post-caldera basalt of Lava Top Butte and the Badlands. The original channel would have extended northeast to join Dry River. The drainage extends uphill to an elevation of 7300 feet (T. 21 S., R. 13 E., Sec. 18) near the north rim of Newberry Caldera. A similar drainage probably existed prior to the caldera-forming eruption about 75,000 years ago. Subsequent eruptions have filled and shifted segments of the drainage. Feature Class: Arroyo Elevation: 4200 feet to 7300 feet County: Deschutes Topographic Quadrangle: Horse Ridge, Evans Well, Fuzztail Butte, East Lake

———————————————
Waterfall is about half mile NW of 10-
Mile Snopark.
A major waterfall along Paulina Creek.
Lava flow from a vent destroyed by
caldera formation forms the step in
topography that has resulted in this
waterfall.
Paulina Creek is undersized for the
features found along the channel; its
average annual discharge is 18 cubic
feet per second. Between 2000 and
4000 years ago a small waterfall
eroded into the caldera-forming tuff
further eroded the tuff to reach
Paulina Lake and dropped the lake’s
level by about 8 feet. This resulted in
a flood with an estimated discharge
rate of about 7000 cubic feet per
second (almost 400 times the annual
rate). The flood lasted no more than
two days. This flood formed the many
large scale features found along
Paulina Creek. Here at Footbridge Falls
during the flood there was a falls
almost 100 feet wide.

average annual discharge is 18 cubic
feet per second. Between 2000 and
4000 years ago a small waterfall
eroded into the caldera-forming tuff
further eroded the tuff to reach
Paulina Lake and drop the lake’s level
by about 8 feet. This resulted in a
flood with an estimated discharge rate
of about 7000 cubic feet per second

Northwest Rift
Zone
Yes LOCATION - eruptive zone located on
the northwest flank of Newberry
Volcano.
Name used by Peterson and Groh
(1965). Also in MacLeod and others
(1995). The name was used informally
in Mckay and others (2009) and by
Robinson and others (2015) on USGS
SIM 3329 featuring the volcano’s
youngest lava flows, but the rift zone is
an important feature that includes lava
flows that have commonly used names
dating to geologic work in the 1960’s
and 1980’s.
———————————————
The rift zone extends from Lava Butte
to the East Lake Fissure.
The northwest rift zone erupted lavas
about 7,000 years ago subsequent to
the catastrophic eruption that formed
Crater Lake and blanketed much of
central and eastern Oregon with
volcanic ash. The northernmost of
these eruptions took place at Lava
Butte; its lavas flowed northwest and
blocked the Deschutes River for a
time. Additional vents and flows
(including the lava flow that hosts
Lava Cast Forest) are present nearly
continuously uphill to the southeast,
cross the north rim of Newberry
caldera and form the East Lake
Fissure. Additional vents broke open
on the upper southwest side of the
volcano and produced the Surveyors

Waterfall Rim No NATURAL HISTORY - provides name for
early Newberry lava flow and highlights
the impact of the glacial history at the
volcano.
———————————————
This rim is located about 3 miles NNE of
B S Well
Early Newberry basalt flow was
faulted, forming an east-facing N-S
rim extending about 3 miles. Later,
water from melting of ice on the upper
part of Newberry Volcano focused at a
low spot on this rim and poured over,
cutting a smooth, water-washed
notch.

Wickiup Draw Yes LOCATION - Wickiup Junction on Hwy.
97 is to the west.
Name used by Donnelly-Nolan and
Jensen (2009)
———————————————
Mouth of draw is about 1.5 mi east of
Wickiup Junction on Hwy 97.
This 8-mile long draw is another of the
major dry channels on the west side of
Newberry Volcano. Now dry, it has
been occupied multiple times by
floodwaters, probably related to
melting ice on the upper parts of the
volcano. The mouth of the draw is
located at an elevation of 4260 feet
(T. 22 S., R. 11 E., Sec. 6). The draw
extends about 8 miles uphill to the
east to an elevation of 5960 feet (T.
22 S., R. 12 E., Sec. 4).
