The natural soil in undisturbed areas are classified as loamy- <br />skeletal, mixed Cryic Paleborolls. These soils have very stony loam <br />surface horizons. They are also very stony in the subsoil and substratum. <br />They are deep in most places but a few small areas have bedrock within 40 <br />inches of the surface. <br />The pH of the A horizon (surface) is 6.2 and conductivity is 0.05 mmhos/cm. <br />The pH of the Bt horizon (subsoil) is 6.6 and conductivity is 0.10 tmnhos/cm. <br />There is adequate topsoil for reclamation purposes in places that have not <br />been previously mined or covered with waste. Wherever possible, the topsoil <br />should be stockpiled to be used in covering the finished site. A final cover <br />of 8 to 12 inches of topsoil should be adequate. <br />Enclosed with this evaluation is ECS-2 giving a list of present vegetation, <br />and ECS-5 giving seeding recommendations for the finished site. <br />Sincerely, <br />~~~.~^+~ <br />J.
