There is no topsoil over the site area. The Cascajo series consists of excessively drained soils that are moderately shallow over. mi:;ed sandy and gravelly materia . The surface layer of these soils is grayish-brown, ver friable coarse sandy loam 4 to 8 inches thick. The subsoil is grayish- brown or brown coarse loamy sand or coarse sandy loam, and it contains some gravel. A layer of gravelly coarse loamy sand is at a depth of 12 to 30 inches. In the lower part of t is layer is a zone where lime has accumulated. Below a depth of ~0 inches is gravelly sand, gravel, or gravelly coarse loamy sand. Water penetrates these soils at a moderately rapid rate. These soils are variable in characteristics but tend to be gravelly and sandy. Gravel is on the surface in some p aces, as is the case at the Pernard Nine Pit. These soils are used mainly for range. The native vege ation is buff alograss, blue grams, sideoats grams, yucca, and son sage. D-~ 1
