APPENDIX B <br />• <br />GENERAL SERIES DESCRIPTIONS <br />BEENOM <br />This is a shallow, well drained soil that formed from sandstone and <br />interbedded shale. Beenom soils are on uplands and mountain sideslopes. <br />Slopes range from 5 to 60 percent at elevations between 5,800 and 7,000 feet <br />on all aspects. So11 permeability is moderate and available water capacity is <br />moderate. The erosion hazard from wind and water is high. Annual <br />precipitation is about 13 inches, average annual air temperature is 48 <br />degrees F and annual frost-free season is 115 days. The dominant vegetation <br />consists mainly of big sagebrush, pinyon-,juniper, and western wheatgrass. <br />Family or higher classification: Loamy, mixed Lithic Argiborrolls <br />DELSON <br />This 1s a deep to very deep, well drained loamy soil which occurs on <br />fans and mesas with a slope of 5 to 80X at elevations between 6,800 and 8,400 <br />ft on all aspects. The soil is formed from basalt colluvlum, has no outcrops <br />and light to moderate coverage of basalt boulders. Soil permeability is <br />moderate and available water capacity is high. The hazard of erosion from <br />wind is slight and from water is moderate. Average annual precipitation is <br />about 17 inches, average annual air temperature is about 44 degrees F, and <br />average frost-free season is about 100 days. The dominant vegetation consists <br />mainly of Gambel oak, serviceberry, big sagebrush and adapted grasses. <br />Family or higher taxonomic classification: Fine montmorillonitic Typic <br />Agriborolls <br />RAZOR <br />This is a moderately deep to deep, well drained, silty clay loam soil <br />which occurs on sideslopes and fans with a slope of 5 to 80X at elevations <br />between 6,000 and 7,000 ft and on all aspects. The soil is formed from <br />locally transported alluvium derived from shale. It has few outcrops and <br />light to moderate coverage of basalt boulders. Soil permeability is slow and <br />available water capacity is moderate. The hazard of erosion from wind is <br />slight and from water is high. Average annual precipitation is about 14 <br />inches, average annual air temperature is about 46 degrees F, and average <br />frost-free season 1s about 115 days. The dominant vegetation consists mainly <br />of Gambel oak, serviceberry, big sagebrush and western wheatgrass. <br />Family or higher taxonomic classification: Fine, montmorillonitic, <br />Mesic Ustollic Camborthids <br /> <br />
