. r <br />Exhibit B - Site Description - Soils Information <br />The proposed affected area has been previously disturbed by historic <br />mining activity and is situated at an elevation of about 9,600 feet on a <br />northwesterly-facing slope. The affected area itself has been denuded of <br />soil and covered for the most part with old mine waste rock. Very small <br />pockets of soil may be found among the disturbance but are insignificant in <br />extent. To the east, south and west, outside the affected area, native <br />soil is present. <br />The area has been described and mapped by the USDA Soil Conservation <br />Service (SCS). The Figure B1 map included herein provides a general <br />delineation of the soils present in the subject area. The Figure B1 map is <br />based on an adaptation of the available SCS data and additional field <br />observations conducted in August, 1987. The soils present are <br />representative of the Schofield-Peeler complex, the Matcher stony sandy <br />loam and a small area of histosols adjacent to Gold Creek. <br />The Schofield-Peeler complex includes soils of both representative <br />soil series but have not been distinguished for the purposes of delineating <br />mapping units. Both the Schofield and Peeler series are fine-loamy, mixed <br />Typic Cryoboralfs and consist of well-drained, sloping to very steep soils <br />that formed in alluvial-colluvial material weathered from granite. <br />Vegetation is lodgepole pine or mixed lodgepole pine and Engelmann spruce. <br />The mean annual precipitation is around 17 to 20 inches, and the mean <br />annual soil temperature is around 34 to 38°F. Permeability is moderate and <br />the available water capacity is low to moderate. Under about a two inch <br />thick layer of forest litter, the surface soil is a light brownish gravelly <br />sandy loam. The subsoil is a brown gravelly sandy loam. Rock fragments
