I • This unit is 50 percent Nortez soil and 40 percent Morapos soil. Included in this unit are small <br />areas of rock outcrop, Maudlin soils, Duffymont soils, and Cochetopa soils. <br />The Nortez soil is moderately deep and well drained. It formed in residuum derived from <br />interbedded sandstone and shale. Typically, the upper 5 inches of the surface layer is dark <br />grayish brown loam. The lower 5 inches is dazk grayish brown clay loam. The upper 16 inches <br />of the subsoil is dark yellowish brown clay loam. The lower 4 inches is yellowish brown <br />channery clay loam. Hazd sandstone bedrock ranges from 20 to 40 inches. <br />Permeability of the Nortez soil is slow. Available water holding capacity is low. Effective <br />rooting depth is 20 to 40 inches. Runoff is medium, and the hazard of water erosion is high. The <br />hazard of soil blowing is slight. <br />The Morapos soil is very deep and well drained. It formed in residuum derived from shale. <br />Typically the surface layer is grayish brown loam 10 inches thick. The upper 18 inches of the <br />subsoil is brown clay loam. The lower part to a depth of 60 inches or more is light yellowish <br />brown calcareous clay loam. <br />Permeability of the Morapos soil is slow. Available water holding capacity is high. Effective <br />rooting depth is 60 inches or more. Runoff is medium, and the hazard of water erosion is high. <br />The hazard of soil blowing is slight. <br />This unit is used for livestock grazing and wildlife habitat <br />149 -Pinelli loam, 3-12% slopes <br />• The Pinelli series consists of very deep, well-drained soils that are found on the benches and <br />alluvial fans. Pinelli soils aze formed in alluvium derived from shale and in loess. Elevation is <br />6,200 to 7,000 feet. The average annual precipitation is 12 to 14 inches, the average annual air <br />temperature is 42 to 45 degrees F., and the average frost-free period is 75 to 95 days. <br />Typically, the upper 6 inches of the surface layer is light brownish gray loam. The lower 12 <br />inches is grayish brown sandy clay loam. The lower part to a depth of 60 or more inches is light <br />brownish gray sandy clay loam. <br />Included in this unit are a few small areas of Evanot and Forelle soils. <br />Permeability of this Pinelli soil is slow. Available water holding capacity is high. Effective <br />rooting depth is 60 inches or more. Runoff is very high, and the hazard of water erosion is <br />moderate. The hazard of soil blowing is low to moderate. <br />This unit is used for native pastureland. <br />160 -Rock outcrop-Torriorthents complex, 50-75% slopes <br />This unit is on hills, cliffs and mountainsides. Elevation is 5,900 to 8,000 feet. The average <br />annual precipitation is 9 to 16 inches, the average annual air temperature is 42 to 48 degrees F, <br />and the average frost-free period is 75 to 105 days. <br />. This unit is 70 percent Rock outcrop and 25 percent Torriorthents and similaz soil. <br />
