" , On218~ . . vegetative type is saltbush on the Torriorthents and sagebrush on the Camborthids. Reclamation potential is poor due to droughtiness and excess salts, UsticTorriorthents, loamy, frigid-Aridic Ar~iborolis, loamy Association, Association #35, (1,140,275 acres) This association consists of nearly level to moderately steep soils on plains or mesas (0-25 percent slopes), Elevations range from 6,000-7,500 feet. The average annual precipitation is 12-15 inches; soil moisture regime is aridic bordering on ustic. Average annual soil tem- perature is less than 470F, frigid, and the frost-free season is 60-90 days, The association has about 60 percent Ustic Torriorthents, 20 percent ~idic Argiborolls, and 20 percent of unidentified minor soils scattered throughout, These soils are located in the north-central area from the Utah State' line to Craig, in Moffat County. Ustic Torriorthents are deep, well-drained soils in mixed alluvium form, from sedimentary rocks. Typically Ustic Torriorthents have a substratum, 10-40 inch layer, Cl horizon, is a light-color~d, loamy material , I I i " light-colored loamy surface layer, Al horizon, about 10 inches thick. The calcareous, loamy material extending to 40 inches+. Hard bedrock is ;1 II ! about 24 inches thick. The underlying layer, C2 horizon, is a light-colored, 40-60 inches+, Ustic Torriorthents are moderately permeable; effective rooting depth " is 40-60 inches. Available water capacity is high and available moisture is influenced by spring and late summer rains; June and July are the \ driest months, Surface runoff is slow, and erosion hazard is moderate.
