<br />1 <br />' ShD--Shingle loam, 3 to 20 percent elopes. This shallow, well <br />' drained soil is on plains and foot slopes. It formed in residuun derived <br />dominantly from interbedded sandstone and shale. The native vegetation is <br />mainly grasses. Elevation is 5,100 to 5,600 feet. The average annual <br />precipitation is 11 to 13 inches, the average annual air te~erature is 51 <br />' to 53 degrees F, and the average frost-free period is 140 to 170 days. <br />Typically, the surface layer is light gray loam about 6 inches thick. <br />The substratim is clay loam about 7 inches thick over weathered shale at a <br />depth of 13 inches. The soil is moderately alkaline. The soils in a few <br />areas have a high content of gypsim crystals. About 20 percent of the <br />t surface is covered by small sandstone channery fragments in some areas. A <br />few areas have a gravelly loam surface layer. <br />' Included in this unit is about 5 percent Midway clay loam on uplands. <br />' The Midway soil is more clayey than this Shingle soil. Also included is <br />about 5 percent moderately deep Minnequa silt loam on concave positions and <br />' foot slopes. Also included are small areas of shale outcrop on steeper <br />breaks. <br />' Permeability of this Shingle soil is moderate. Available water <br />' capacity is very low. Effective rooting depth is 4 to 20 inches. fhmoff is <br />slow to very rapid, and the hazard of water erosion is slight to very high. <br />' This unit is used for rangeland. <br /> <br /> <br /> <br /> <br />:~ <br /> <br /> <br />
