Soil Profile and Geologic Information <br /> The Site is mapped on the Preliminary geologic map of Cenozoic deposits of the Bellota <br /> quadrangle, California (Marchand and Bartow, 1979). The western half of the Site is <br /> depicted within a map unit of Holocene alluvium. The eastern half of the Site is <br /> depicted within a map unit of the Modesto formation upper member, described as <br /> .1arkosic alluvium forming Mokelumne River terraces and alluvial fan; chiefly sand with <br /> minor gravel and silt; probably glacial outwash" (Plate 7). <br /> The surface and near surface soils located at the Site are reported by the USDA Web <br /> Soil Survey to be composed of Columbia fine sandy loam, Tokay fine sandy loam, and <br /> Vina fine sandy loam (Plate 8) (USDA, 2009). The table below presents some selected <br /> properties of these soils: <br /> Table 1.

The boring was four inches <br /> in diameter, 3.30 feet deep, and was excavated by hand auger (Table 2). The location <br /> of the boring is indicated on Plate 9. <br /> LOGE 1209 Page 4 <br />
