We are happy to provide this information to you. If we may be of further ass- istance please feel free to contact us. The area proposed for excavation has one major soil and inclusions of a small amount of steep soil on the East Boundary. Descriptions of the soils and their characteristics can be found on the attached sheets. The climate Precipitation averages 20-25" per year. Over one- half comes as snow. Growing season is from May 15 to July 15. The Topography Elevation is approximately 6700'. The slopes range from 9-15~. The vegetation Ttlere are two distinct plant communities on the proposed excavation area. The area north of the fence is non- irrigation pasture. Intermediate wheatgrass, along with timothy and smooth bromegrass make up 85% of the production by dry weight. Other plants found in this pasture are big sagebrush, Kentucky Bluegrass, dandelion, western yarrow, and a few annual weeds. The ground cover was estimated to be 1800 pounds of air dry forage per acre. The area south of the fence is mostly in an old excavation. The plants are mostly weeds such as Canada thistle, Russian Thislte, cheatgrass, tarweed, prostrate knot- weed, and dandelion. There is some western wheatgrass, big sagebrush rabbitbrush, and a very small amount of sueetclover. The ground cover density is about 10% with production being about 200 pounds per acre. There is a small wet area on the southern boundary of the area which is also an old excavation; the plants found in it are cattails rushes and sedges.
