They <br />formed in gravelly and cobbly alluvium and elevation ranges from b,000 to <br />8,500', The average annual precipitation ranges from 14 to 19", thu ;~ver,ege <br />annual air temperature is 45-50 degrees F., and the averafc frosC free season <br />is t00 to 130 days. <br />These soils vary considerably but generally, tt+e Us tic ?'orricrthents surface <br />layers are gravelly or cobbly loam, or fine sandy loam. The substratums <br />are very gravelly or cobble outwash materi8l. Generally, the UsLOllic Hap- <br />largids surface layers arc gravelly or c.cbbly loam or fine santly loam. <br />The subsoils are very cobbly or very gravelly loam, sandy clay loam, or <br />fine sandy loam.. The substratums are very gravelly or copbiy outwash material. <br />Permeability of these soils vary depending on the texture of the parent <br />material, Effective rooting depth is 40" or.more and avaiiable water cap- <br />acity is low. Surface runoff is rapid and the water erosion hazard is high. <br />This soil type is used primarily for rangeland or wildlife habitat and for <br />construction gravel. <br />Native vegetation consists mainly of western wheatgrass, Indlan ricegrass, <br />needleandthread, blue grams, mutton grass, fenders threeawn, ~unegrass, <br />big sagebrush, rabbitDrush, pinyon pine, Aoeky Mountain juniper, Pontlerosa <br />Pine, Mountain mahogany, serviceberry, snowberry and Cambel oak, Wildlife <br />found on this site intlude mule deer, cottontail rabbit, coyote, squirrels <br />and various bird species. <br />Steep slopes, gravel and cobble, arc the primary limitin6 soil features <br />when planning for home or com^;unity construction, These soil features <br />` affect excavation for foundations, uti]ity lines and roads. Construction <br />of sanitary facilities is severly ]invited and of'f site disposal systems <br />ere more feasible. <br />
