" 002190 The aSsocei.OIl has ahout 60 percent ^ridiergiho[o1.1s, 20 percent Aridlc Haploborolls, cJnd 10 percent of unidentified minor soils, near Meeker in Rio Blanco County. Aridic Argiboro1ls are moderately-deep, well-drained soils on clayey' sedimentary rocks. Typically they have a 'dark-colored, clayey surface layer, Al horizons, 7-20 inches thick, that does not crack to the surface. The subsoil, 10-40 inch layer, B2t horizon, is a light to dark-colored, clayey material, with thin clay films on the ped surfaces. The substratum is fractured bedrock (shale). Permeability is slow; effective rooting depth is 20-40 inches. Available water capacity is moderate-high; surface runoff is rapid and erosion hazard is high-very high. Aridic Haploborolls are deep, well-drained soils on clayey sedimentary rocks. Typically they have a dark-colored, clayey surface layer, A1 horizon, 7-20,inches thick, that becomes dry during the growing season, The subsoil, 10-40 inch layer, B2 horizons, is a dark to light-colored, clayey material. The substratum is fractured bedrock (shale). Permeability is slow; effec- tive rooting depth ranges from less than 20 inches to 40+. Available water capacity is low to high; surface runoff is rapid and erosion hazard is high-very high. Sedimentation yield from this association is 0.5-1.0 acre-feet/square mile/year, These soils are used mainly for urban develop- ments, range, and wildlife. General vegetative type is pinyon-juniper. Reclamation potential is fair due to excess slope. Typic Cryoborolls, loamy-Rock outcrop Association, Association #55, (139,819 acres) This associatio~ consists of sloping to steep soils on mountain slopes and benches (9~25 per~ent slopes).'
