This unit has been deposited by the MissouriRiver. The approximate upper 15 feet of these deposits are composed predominantly of silt withvariable amounts of clay and organic material. Material residing below the silt is predominantlysand and gravel to the top of bedrock. Thickness of this unit ranges from 80 to 100 feet. Thewater table is approximately five to 15 feet below ground surface, resulting in an interval ofsaturated sand and gravel greater than 80 feet thick.This unit is a wind-blown deposit of silt and clayey silt with occasionalpockets of clay, sand and gravel. The unit is composed of two separate loess layers, the Roxanabelow and the Peoria above (Goodfield, 1965). Total thickness of the two units may reach140 feet. The Roxana is higher in clay content and may have a paleosol developed in the upperfew feet. The contact between the two units forms a potential slide plane in areas of hightopographic relief. The loess overlies Mississippian-age bedrock comprised of limestone andshale creating two unique environments. Where the loess is thin, the limestone may be karstic.Where the underlying unit is predominantly shale, water will perch, destabilizing the contact zone.Where the loess rests on shale, the slide potential is increased.

Deposits of clayey till are located in the western portion of the WeldonSpring quadrangle. Quarternary till was deposited as a drift blanket during glaciation northof the Missouri River. The till is a mixture of clay, silt, sand, gravel and cobbles that covers thebedrock surface. The till varies in thickness from 10 to 25 feet with the thickest deposits inlandfrom the river and in depressions of the bedrock surface.Terrace deposits in this area are slightly differentthan previously mapped terrace deposits (Brill, 1991; Harrison, 1997; and Goodfield, 1965). Allwere deposited during fluvial events, leaving the terrace above low flow stage of the river.However, the terrace deposits in this area have a lacustrine signature of sensitive organic claysapproximately 20 feet below the surface. After high stage flow returned to normal, low lyingareas within the terrace were filled with organic clay material. This zone has a very low shearwave velocity and underlies considerable infrastructure.

Areas of residual material are found on the slope and toe slope of high reliefareas. Content is dependent on the bedrock parent material but typically has high claycontent with fragments of parent material.Exposures in these quadrangles are typically found in areas ofhigh topographic relief.

Line locates the placement of the cross section with end line symbols.Public Land Survey System including Spanish land grants.

The Weldon Spring and Chesterfield quadrangles include part of the floodplain of the Missouri River. Thefloodplain is up to three miles wide in this area. The Weldon Spring, Chesterfield and Manchester quadranglesinclude portions of the loess covered uplands and lie within the Dissected Till Plains Section of the CentralLowlands Province of the Interior Plains Physiographic Division. The House Springs and Maxville quadrangles liewithin the Salem Plateau Section of the Ozark Plateau Province of the Interior Highlands Physiographic Division.The lowest recorded elevation is 390 feet mean sea level (msl) and occurs along the edge of the Meramec Riverin the eastern corner of the Maxville quadrangle. The highest recorded elevation is 940 feet msl and occurs in thenortheastern corner of the House Springs quadrangle. Total relief of the five quadrangle area is approximately550 feet.

The five quadrangle area is underlain primarily by deposits of Paleozoic limestone and shale. The majority of theChesterfield quadrangle and the northeast portion of the Maxville quadrangle are underlain by Mississippian-ageSt. Louis, Salem and Warsaw formations. The majority of the Weldon Spring quadrangle through the northwestcorner of the Maxville quadrangle is underlain by the Mississippian-age Burlington-Keokuk Formation. Thesouthwest corner of the Manchester, majority of the House Springs, and southwest corner of the Maxvillequadrangle are underlain by Ordovician-age St. Peter, Joachim and Plattin formations.

The Seismic Cone Penetrometer Testing (SCPT) data from the Chesterfieldquadrangle displays averaged shear wave velocities (Vs). The nine SCPTresults show the distribution of a majority of the borings are between 175and 250 meters per second (m/s).

Shear wave velocity testing was conducted in the Chesterfield quadrangleduring June of 2010. Seismic Cone Penetrometer Testing is displayed above.

The Missouri Department of Natural Resources, Division of Geology andLand Survey, Geological Survey Program would like to recognize thecontributions to the project by the Missouri Department of Transportationfor their Seismic Cone Penetrometer Testing, and the Missouri Universityof Science and Technology staff and Ali Atef for their Shallow SeismicRefraction surveys and analysis.
