2.04.9 <br />A soils survey was performed on July 18, 2003 for the area to be disturbed <br />by the new gob pile. The soils report is presented in Volume III, Tab 7. The <br />survey area is within the Torriorthents-Haplarg ids complex, very stony. <br />Haplargids are deep and well drained. These soils are highly variable, and <br />profile development is weak to moderate. In some areas a thin dark colored <br />surface layer is forming. The surface layer most commonly is loam or sandy <br />loam and is very stony. The subsoil is loam, clay loam, or light clay and has <br />cobbles and stones. Content of rock fragments exceeds 35 %. <br />39 — Fughes Loam, 25 to 65 percent slopes. <br />This is a deep, well drained soil. It formed in old alluvial fan and landslide <br />deposits and is on alluvial fans, valley side slopes, and uplands. Elevation <br />ranges from 6,500 to 8,500 feet. Average annual precipitation is about 18 <br />inches, average annual air temperature is about 37 degrees F, and the <br />average frost -free season is about 100 days. <br />Typically the surface layer is very dark grayish brown loam about 5 inches <br />thick. The subsoil is dark grayish brown clay loam that grades to reddish <br />brown light clay and is about 39 inches thick. The substratum, to a depth of <br />60 inches, is light reddish brown clay loam. <br />Permeability is slow, and available water capacity is high. Effective rooting <br />depth is 60 inches or more. Surface runoff is rapid and very rapid. The <br />hazard of erosion from wind is slight and from water is high. <br />Included with this soil in mapping are a few small areas of Curecanti, <br />Cochetopa, and Bulkley soils and small areas of well drained alluvial land <br />along drainageways. Slips can occur on steeper slopes, especially if the <br />area is disturbed. Interbedded sandstone and shale crop out in some of the <br />steeper areas. <br />Most areas of this soil are used for grazing of livestock and wildlife and for <br />recreational purposes. <br />PR-14 2.04-98- 03/14 <br />
