EXHIBIT 1--SOILS INFORMATION <br /> On the upper part of the slope the soil-mapping unit is Curecanti gravelly sandy <br /> loam, 4 to 10 % slopes. This deep well drained soil formed in alluvium. Typically the <br /> surface layer is gravelly sandy loam about 10 inches thick. The subsoil is very cobbly <br /> clay loam about 18 inches thick. The substratum to a depth of 60 inches is extremely <br /> cobbly sandy loam. Average annual production of air-dry vegetation is approximately <br /> 850 pounds per acre. On the lower part of the slope the soil mapping unit is Troutdale- <br /> Rogert, warm, complex, 2 to 15% slopes. This unit is about 65% Troutdale soil and <br /> about 20% Rogert soil. The Troutdale soil is mainly in grassy, concave shaped, areas. <br /> The Rogert soil is on hills and ridges. The Troutdale soil is moderately deep and well <br /> drained. It formed in alluvium over residue derived dominantly from schist and gneiss. <br /> Typically the surface layer is loam about 7 inches thick. The subsoil is sandy clay loam <br /> about 15 inches thick. Soft weathered schist is at a depth of 22 inches. The Rogert soil is <br /> shallow and well drained. It formed in residuum derived from gneiss or granite. <br /> Typically the surface layer is very gravelly sandy loam about 5 inches thick. The, <br /> substratum is extremely gravelly sandy loam about 12 inches thick. Gneiss is at 17 <br /> inches. The average annual production of air-dry vegetation is approximately 800 <br /> pounds an acre on the Troutdale soil and 600 pounds an acre on the Rogert soil. <br /> However, in the present condition the production figures would be lower on this specific <br /> site. Basal ground cover was approximately 28 percent. Dominant species are blue <br /> grams, fringed sage, pingue, threeawn, western wheatgrass, broom snakeweed, and other <br /> forbs. <br /> 11 <br />
