• hazard of erosion is slight to very high. The potential plant community <br />is scattered pinyon and juniper with an understory of grasses. Land uses <br />include rangeland, wildlife habitat, and noncommercial woodland. <br />p 102 Seitz gravelly fine sandy loam. This deep, well drained soil on <br />north-facing mountainsides was formed in alluvium and colluvium. <br />Typically, the surface layer is pinkish gray, gravelly fine sandy loam 15 <br />inches thick. The upper 9 inches of the subsoil is very gravelly clay <br />loam. The next 10 inches is very cobbly clay. The underlying material <br />to a depth of 60+ inches is very cobbly sandy clay loam. The soil is <br />neutral. Slope is 20 to 40 percent. Permeability is slow, available <br />water capacity is moderate, runoff is rapid, and the hazard of erosion is <br />very high. The potential plant community is mainly Douglas fir with an <br />understory of common juniper, buffalo berry, grasses and sedges. The unit <br />is used for woodland, wildlife habitat, and recreation. <br />• p 104 Shanta loam. This deep, well drained soil found on stream terraces <br />was formed in alluvium. Typically, the surface layer and subsoil are <br />brown loam about 43 inches thick. The substratum to a depth of 60+ inches <br />is stratified sandy loam and loamy sand. The soil is mildly alkaline to <br />a depth of 2 inches and moderately alkaline below that depth. Slope is <br />0 to 3 percent. Permeability is moderate. Available water capacity is <br />high. Runoff is slow and the danger of erosion is slight. The potential <br />plant community is mainly grassland. Its major uses are rangeland and <br />non-irrigated pastureland. <br />N 105 Shanta Loam, dry. This deep, well drained soil of stream terraces <br />formed in alluvium. Its slope is 0 to 3 percent. typically, the surface <br />layer is grayish brown loam about 27 inches thick. The substratum to a <br />depth of 60+ inches is stratified sandy clay loam, loam, and silty clam <br />loam. The soil is mildly alkaline to a depth of 48 inches and moderately <br />alkaline below that depth. Permeability is moderate, available water <br />capacity is high, runoff is slow and the danger of erosion is slight. The <br />• potential plant community is grassland. The unit has a potential as <br />irrigated cropland but in this area would probably be used as non- <br />irrigated rangeland. <br />2.04.9-11 <br />
