• accounts for inclusions end soil lose during selvage due to brush clearing. %BF-Ninevsda•splitro Complex. Th1s map unit is located on the very steep bedrock controlled sideslopes end ridges. All inclusions within this map unit have unsuitable rock fragment contents at or Weer the surface. Na recoverable soil is available from this map unit due to very steep slopes and excessive rock fragments (Addendum 8, Tab 9). 11C, 11D-Binco Silty Clay Loem. The Binco silty clay loam map units occur on the gently sloping to moderately steep colluvial fans end residual sideslopes, benches, and toeslopes. The soil profile is deep ri th a thin light colored surface horizon which overlies a clay subsoil end substratum. Adjacent Aaberg soils have moderately deep profiles. Buckskin soils have a dark colored surface horizon and subsoil clay accumulation. the recommended soil salvage thickness is based on [he thickness of the surface horizon since subsurface clay levels are unsuitable. Soil salvage should be terminated near the upper part of the Iambic (Bw) horizon. The mean in situ suitable soil thickness for 13 profiles is 6 inches (Addendum 8, Tab 9). • The 11C and 11D map units consist of 90 percent Binco with 5 percent each of Aaberg and Buckskin (Addendum 3, Tab 9). A 0.5-f oot mean salvage thickness was used for these map units to calculate recoverable soil volumes listed in Table 1 and Exhibit 9-1. 12C and 12D-Buckskin Clay Loam. Buckskin clay loam soils occur on gently sloping to moderately steep mountain sideslopes, benches, tans, small knolls, and ridgetops. The soil profile is deep and yell developed with a dark Colored surface horizon and subsoil clay accumulation. This soil has a thinner surface horizon than either Cochetopa or Routt. Adjacent Aaberg end Binco profiles lack a mollic epipedon and argillic horizon. The recommended soil salvage thickness is based solely on the thickness of the surface mollic epipedon and adjacent, untlerlying transitional horizons. Soil salvage should he terminated at the top of the argillic (Bt) horizon. The mean in situ suitable soil thickness for 16 profiles is 9 inches (Addendum B, Tab 9). _ The 12C end 120 map units consist of 75 percent Buckskin rith 10 percent Binco and 5 • percent each of Buckskin variant, Aeber g, and Routt inclusions (Addendum 3, Tab 9).
