(102) Perms-Hesperus complex, 25 to 65 percent slopes - Contd. <br />• <br />This unit is 45 percent Perms and 30 percent Hesperus. Also in this <br />unit is about 25 percent minor soils. The components of this unit are <br />so intricately intermingled that it was not practical to map them sepa- <br />rately at the scale used. <br />The Perms soil is deep and well drained. It formed in alluvial de- <br />posits. Typically, the surface layer is dark grayish brown very cobbly <br />loam about 11 inches thick. The upper 19 inches of the underlying <br />material is light yellowish brown extremely cobbly sandy loam. The <br />lower part to a depth of 60 inches is light yellowish brown extremely <br />cobbly loam sand. <br />Permeability of the Perms soil is moderately rapid. Available water <br />capacity is low. Effective rooting depth is 60 inches or more. Runoff <br />is rapid, and the hazard of water erosion is moderate. <br />• The Hesperus soil is deep and well drained. It formed in material <br />weathered from sandstone. Typically, the surface layer is dark brown <br />loam about 10 inches thick. The upper 8 inches of the subsoil is dark <br />brown clay loam. The lower 31 inches is yellowish brown clay loam. The <br />substratum to a depth of 60 inches is yellowish brown sandy clay loam, <br />Permeability of the Hesperus soil is moderately slow. Available water <br />capacity is high. Effective rooting depth is 60 inches or more. Runoff <br />is rapid, and the hazard of water erosion is high. <br />Included in this unit are small areas of Savage, Moyerson, and Rock <br />outcrop. <br />This unit is used mainly for Livestock grazing and wildlife habitat. <br />LJ <br />
