General vegetative group is mountain shrub-sagebrush. <br /> <br />Reclamation potential is fair-poor due to excess' slope. <br /> <br />Lithic Haploborolls, skeletal-Rock outcrop Association, Association~ <br /> <br />(9,502 acres) <br /> <br />This association consists of moderately steep and steep soils on <br /> <br />mesas and breaks (15 to 25+ percent slopes). Elevation ranges from <br /> <br />7,000-8,000 feet. The average annual precipitation is 15-20 inches; <br /> <br />moisture regime is ustic. Average annual soil temperature is more than <br /> <br />32'F but less than 47'F, cryic; frost-free season is less than 90 days. <br /> <br />The association has about 60 percent Lithic Haploborolls and 40 percent <br /> <br />rock outcrop, located near Meeker in Rio Blanco County. <br /> <br />Lithic Haploboralfs are shallow, well-drained soils on sedimentary <br /> <br />rocks. Typically they have light-colored, very gravelly surface layers, <br /> <br />Al horizons, less than 7 inches thick. The subsoil, 10-20 inch layer, <br /> <br />B2 horizon, is a very gravelly soil material over fractured sedimentary <br /> <br />rocks. Permeability is moderate; effective rooting depth is less than <br /> <br />20 inches. Available water capacity is low; surface runoff is medium and <br /> <br />erosion hazard moderate, Rock outcrop consists of exposures of bare <br /> <br />rock. Sediment yield from this association is 0.5-1.0 acre-feet/square <br /> <br />mile/year. The soils are used mainly for range and wildlife. General <br /> <br />vegetative group is mountain shrub-aspen. Reclamation potential is poor, due to <br /> <br />excess slope and coarse fragments, or rock outcrop. <br /> <br />0'11,21 <br /> <br />-.-- <br /> <br />.1,J:.~.. , <br /> <br />
