FOILS '.+:FORNA?:04 <br />• <br />how each soil can be expected to perform in a reclamation environment as well as a <br />description of any characteristics of each soil which should betaken into account <br />during the salvage, replacement, and/or revegetation. <br />S.C.S. SOIL SERIES DESCRIPTIONS: <br />SCHAMBER-RAZOR COMPLEX: This soil is derived from the eroded breaks and <br />remnants of granite outwash from the Pikes Peak area. It overlies shale. Average <br />annual precipitation is about 13 inches. This complex is made up of about 90~ <br />Schamber, 30$ Razor, and 30~ other soils including areas of the Chaseville-Midway <br />Complex, Kim loam, Razor stony clay loam, and the Heldt clay loam. <br />The Schamber soil (Figure 1) is typically gravelly on the surface and has a <br />r 1 <br />U <br />gray color. The soil is highly permeable with a limited available water capacity. <br />The erosion hazard is moderate. The effective rooting depth is about 60 inches. <br />In contrast, the Razor soil (Figure 2) is clayey, being derived from a <br />calcareous shale. It is a heavy soil, with a low permeability and a moderate to <br />high erosion hazard. The effective rooting depth is about 20 to 90 inches. This <br />soil is generally not directly associated with any gravel deposits and therefore <br />should be a good indicator of where gravel is NOT present or where overburden <br />depths are considerable. <br />Vegetation on the Schamber is fairly typical prairie growth dominated by <br />C 1 <br />wheatgrasses and gramas with some four-wing saltbush, buckwheat and skunkbush <br />sumac. The Razor soil, on the other hand, supports a rather different growth <br />dominated by alkali sacaton, wheatgrasses, and a limited amount of grams, plus a <br />good deal of galleta. If princeplume, two-groove milkvetch, and/or Fremont <br />goldenweed are present, it is indicative of a notable amount of selenium present <br />in the soil. <br />page 2 of 7 Exhibit I <br />
