Uintah County is located in the central portion of the Uinta Basin, which
extends sixty miles into western Colorado. The northern rim of the basin is
formed by the Uinta Mountains, the western rim by the Wasatch Mountains, and the
southern rim by the Roan and Book cliffs. The basin is the geological remains of
prehistoric Uinta Lake, formed during the late Tertiary period, the same period
when sediment was deposited in the lake bottom to form gilsonite, oil shale, tar
sands, and oil. Ashley and White Creek and the Uinta and Green rivers are major
water resources in the county. The Green, the largest of the four, slices
through the central portion of the county.
The dominant industries in Uintah County are cattle, hay and alfalfa, lumber,
mining, oil and gas. Uintah County consists of 4,487 square miles of land and
62% of the land is shrub/rangeland.
Average low winter temperatures: 16ºF; average high summer temperatures:
