Occurring primarily in Utah, the Uinta Basin Floor ecoregion lies in a large synclinal basin enclosed by the Uinta Mountains and Tavaputs Plateau. Precipitation is low and soils are arid. Winters are constantly cold and often foggy due to frigid, dense air draining from the adjacent uplands and resultant air temperature inversions. Saltbush-greasewood is the natural vegetation type. Ecoregion 20f is distinguished from other arid basins by the abundant stream runoff it receives from the mountains in Utah. Streams are often diverted for irrigation. Alfalfa, small grain, and corn are grown for silage on arable, gently-sloping terraces and valley floors. Stonier soils are irrigated for pasture where and when water is available. Non-irrigated areas are used for livestock grazing.
