Uinta County lies in the southwestern corner of Wyoming, and represents the southwestern section of the state as far as the plant) life and soils are concerned. The material for this paper was all secured in Uinta County which is now in the process of being soil surveyed. Uinta County lies at the northern edge of the Uinta Mountains which are mainly in Utah. The eastern fourfifths of the county slopes northeastward and is drained by Blacks Fork of the Green River, Muddy creek, and Cotton wood Creek into the Green River. The western fifth of the county drains northward into Bear River and Great Salt Lake. The altitudes range from 6279 ft. at Granger a few miles from the northeast corner of the county to over 9500 ft. along the southern boundary where the foothil's of the Uintiv Mountains enter the county. Evanston, in the west central part of the county, has an elevation of OStiO ft,, while fifteen miles farther north where the Bear River leaves the county the elevation is a', out 500 ft. lower. The soils of this section of Wyoming have a similar range in Great Soil Groups from the Gray Desert to the Podzol soils as are found crossing the United States east and west, as are reported on for Russia by Glinka, and also in the northern part of Wyoming by Thorp. The rainfall at Green River is 6 34 inches 30 miles east of the northeastern corner of Uinta County, while at Evanston, midway of the western edge of the county, the rainfall is 14.19 inches in an altitude of 6860 ft.* This would indicate a rainfall of around 10 inches for the region of Gray Desert soils, about 15 inches for the Light Brown soils, and probably about 20 inches or over in the mountains where the Podzol soils are foundThe mean temperature at Green River is 42,6F and 39.6F at Evanstown. At the higher elevations where the Podzol soils develop it is probably several degrees lower. The variation in lower temperature and higher rainfall with the increase in elevation tends to affect the soil and vegetation to a greater degree than would be the case with one of these factors alone.
