Mapping Units 2VD, 2VF <br />• Routt loam <br />This is a deep, well-drained soil on gently sloping to moderately steep <br />benches and mountain sideslopes of 3 to 65 percent. It formed in mixed <br />colluvium and residuum. This series is common along the ridge dividing <br />Mines 1 and 2, along Middle Creek in the 16284 Lease and over a considerable <br />area south of Pinnacle Peak. Native vegetation is aspen and sagebrush. <br />A considerable portion was farmed previously, but is now in perennial <br />pasture grasses. <br />Included in this unit are Coutis fine sandy loam (34 E), Buckskin (2) <br />loam, and Cochetopa fine sandy loam (SOC). <br />• Typically the surface layer is very dark grayish brown to brown loam <br />about 26 inches thick. The upper subsoil layer is yellowish brown clay <br />loam about 12 inches thick, with light gray uncoated sand grains occuring <br />on the faces of peds. The lower subsoil is yellowish brown and light <br />yellowish brown heavy silty clay loam extending to 60 inches or more. <br />Permeability is very slow. Effective rooting depth is 60 inches or <br />more. Available water capacity is high. Surface runoff is medium. <br />Erosion hazard is high from water. <br />n <br />U <br />-4- <br />i ... <br />
