<br />EXHIBIT I - SOILS INFORMATION <br />Topsoil has been salvaged from previous workings. A survey <br />of the site soils cvas prepared by the United States Department <br />of Agriculture, Soil Conservation Service, in Durango, Colorado <br />for the Cugnini's in the fall of 1992 for the purpose of this <br />report. The soils types are delineated on the accompanying <br />map with the particular soils types described below. <br />The soil mapping units that occur on the area to be <br />disturbed are classified as the Ustic Torriorthents- Ustollic <br />Haplargids complex with 12- 16 percent slopes This map unit <br />is on terraced edges, mesa edges and hillsides. Elevation is <br />6,000 to 8,500 feet in elevation. The unit is 50 percent Ustic <br />Torriorthents and 30 percent Ustollic Haplargids. The Ustollic <br />Haplargids are in the less sloping areas. <br />Ustic Torriorthents are deep and somewhat excessively <br />drained. These soils formed in outwash. No single profile <br />of Ustic Torriorthents is typical, but one commonly observed <br />in the survey area has a surface layer of gravelly or cobbly <br />loam or fine sandy loam. The subsoil is very cobbly or very <br />gravelly loam, very gravelly or very cobbly sandy clay loam, <br />or very gravelly or very cobbly fine sandy loam. The substratum <br />is very gravelly or very cobbly outwash. <br />Permeability of these Ustic Torriorthents and Ustollic <br />Haplargids varies depending on the texture of the parent <br />material. Effective rooting depth is 40 inches or more. <br />Available water capacity is low. Runoff is rapid, and the hazard <br />of erosion is high. <br />This unit is used mainly for wildlife habitat, as rangeland, <br />and as a source of construction material. <br />Another type of soil found in the area is the Falfa Clay <br />Loam which is a well-drained soil on the mesa tops. It formed <br />in calcareous loess. <br />Typically, the surface layer is reddish brown clay loam <br />about 9 inches thick. The upper part of the subsoil is reddish <br />brown clay loam about 5 inches thick, the next part is reddish <br />brown clay about 20 inches thick, and the lower part is reddish <br />brown clay loam about 23 inches thick. The substratum is <br />yellowish red clay loam that extends to a depth of 60 inches <br />or more. <br />Included in this unit are about 10 percent Corta Loam, <br />5 percent soils that are similar to this Falfa soils but have <br />a dark-colored surface layer, and small areas of Witt loam and <br />
