Box 225 <br />Florence, CO 81226 <br />Re: North Area: Soils information pertaining <br />to available topsoil for Phase IV i; V. <br />Dear Li, <br />In January 1983 soil samples were taken for the purpose of determining the amount <br />of soil suitable for reclamation based on classification and chemical an aylsis. <br />Four sites were examined shown on soils map # - Ste-Satanta <br />Topsoil Subsoil <br />Sites Depth Depth <br />#1 4-6" 36" <br />#2 6" 24" <br />#3 6" 30" <br />average depth of Satanta topsoil <br />and subsoil available for <br />reclamation - 30" <br />Three soil samples were taken at site #2. <br />0 - 6" 6 - 18" and 18" - 30" <br />See chemical analysis chart # <br />Soil Sample on Site #4 <br />0-6" <br />See Chemical analysis chart # <br />The Tecolote and the Pojoaque Variant-Sedillo complex soils have a thin very <br />gravelly or stony surface layer 0-3" thick with a very gravelly subsoil. These <br />two soils are very poor sources of topsoil due mainly to the thin surface layer <br />and the large stones and ,fragmented material on the surface and in the subsoil. <br />The only available soils in the area that I would recommend for saving as a <br />suitable plant medium would be from the Satanta Series. This soil is located <br />on the terrace tops, the amount of suitable top soil decreases nearer the terrace <br />edges. <br />In determining the average depth of topsoil that could be used, 30" over the <br />Satanta Series area would be a realistic figure to use in determining topsoil <br />yardages. <br />Si~rely <br />r~ <br />O Tfte Soil Conservation Service <br />U is an agency of the <br />Department of Apr¢ulture <br />SCS-AS-1 <br />10-79 <br />
