Soils Information Exhibit I <br />Soils at the site appear to be as represented on the current NRC5 map. Test holes have been <br />dug on the site to determine topsoil, overburden and gravel depths. These can be seen in the <br />mining section. The soil types for the permit are listed below. They are also shown on Map C- <br />1. <br />Soil Identification Soil Description <br />65 Torrifluvents This broadly defined unit consists of deep, well drained to somewhat <br />poorly drained, neazly level soils on flood plains adjacent to to <br />Colorado and Roarinf Fork Rivers and their major tributaries. Slope <br />is 0 to 6 percent. The soils formed in alluvium. <br />These soils are stratified and vary widely in texture and depth. The <br />surface layer ranges from loamy sand to fine sandy loam to silty loam <br />to clay loam. The underlying layers are generally sandly loam or loam <br />stratified with sand, gravel, and cobbles. In some areas gravl and <br />cobbles are on or near the surface. <br />27 Halaquepts This broadly defined unit consists of deep, somwhat poorly drained to <br />poorly drained, nearly level and gently sloping, salt-affected soils in <br />narrow foothill valleys, on fans, and on low terraces. Slopes are 0 to 6 <br />percent. These soils formed in alluvium. <br />The soils are extremely variable. The upper 24 inches ranges from <br />loam to clay, and the underlying layers are generally gravelly. The <br />soils are commonly gleyed from the surface down. Stratified sand, <br />gravel, and cobbles aze at a depth of 24 to 40 inches. In some azeas, <br />gravel and cobbles are at or near the surface. <br />4!26/04 Page 1-1 <br />
