Section 779.21 (a) Continued. <br />These soils are used almost entirely as rangeland although wildlife <br />also utilizes the range along with the cattle and sheep. <br />Vegetation is mostly Gambell oak, big sagebrush, Idaho fescue, and <br />wheat and blue grasses. There are a few areas of ponderosa pine <br />and aspen. <br />Cold climate severely limits agricultural potential. Low strength, <br />shrink-swell, and frost action are limiting to most nonagricultural <br />uses. <br />In 1972, the U. S. Department of Agriculture Soil Conservation <br />Service ("SCS") prepared a general soils map of Routt County. The <br />area which corresponds with the Twentymile Park Area is shown on <br />the Twentymile Park Suils (Map 28). <br />• Site specific soils work was initiated by the SCS on undisturbed <br />parts of the permit area and in particular, Energy Mines No. 1 and <br />2 in 1975. Subsequent soil mapping was conducted o^ these lands <br />during the summer and fall of 1976. The mapping intensity utilized <br />by the SCS was the order "two" sampling intensity. All of the <br />soils maps prepared for the Energy Mines No. 1 and 2 were mapped <br />under this program. <br />Energy Fuels had the SCS conduct a high intensity order two survey <br />for the Eckman Park area Suring August of 1978. Flapping units were <br />mapped as small as 7 acres in size. Additional soils surface work <br />was performed by Energy Fuels in February of 1979 when over 120 <br />detailed soil cores, and in 7uly of 1979 when an additional 235 <br />auger holes were taken to confirm the accuracy of the previous <br />mapping unit boundaries estab:ished by the SCS. The holes sampled <br />in February were taken using a two and seven-eighths drill probe. <br />Detailed field notes, photographs and measurements were taken on <br />• each hole.
