They formed in residuum <br />and sediments weathered from interbedded shale and arkosic sandstone. <br />Elevation is about 5000 to 6800 feet. Aversge annual precipitation is <br />about 1L to 17 inches. :lean annual air temperature is about l~7°F. Bresser <br />soils are about 50 percent of the unit and Cushman soils are about 25 <br />percent. Included in gapping and making up about 25~ of the unit are small <br />areas of sandstone outcrop, Truckton, Ascalon, Kutch, Renohill, Wiley <br />and Baca soils. <br />Typically Presser soils have a grayish browci surface layer about <br />~,,, <br />7 inches thick. The subsoil is t:roant sandy clay loam about 22 inches <br />thick, The substratum is very pale brown loamy sand. <br />Permeability is moderate. The effective rooting depth is 60 <br />inches or more: Available water capacity is moderate. Surface <br />runoff is medium and erosion hazard is moderate. <br />The Cushman is a moderately deep, well drained soil. It occurs on <br />slope breaks, steep side hills and saddle areas where it formed in <br />residuum weathered from interbedded shale and sandstone. <br />Typically Cushman soils have grayish brown loam surface layers <br />about t; inches thick. The subsoil is brown clay loam about 20 inches <br />thick. The subsoil is underlain try soft interbedded shale and sandstone. <br />x. <br />i <br />{,.: <br />
