History

Uinta County was created on December 1, 1869, by the legislature of the Wyoming Territory, with its temporary seat located at Fort Bridger.^[4][5]

Originally, it ran along the entire western border of Wyoming, including Yellowstone National Park.^[6] The county was named for Utah's Uinta Mountains, which are visible from many places in the county.^[7] The county was given its present boundaries in 1911 when Lincoln County was carved out of the northern part of Uinta County.^[4]

Geology

The 161 km wide western North American Fold and thrust belt extends from Alaska to Mexico, forming several northerly trending thrust faults in southwest Wyoming, including the Crawford, Absaroka and Hogsback (Darby), which formed from the Late Jurassic through the early Eocene. The Painter Reservoir Field^[9] was discovered in 1977 from the 407 m thick Nuggest Sandstone which forms an anticline structural trap in the hanging wall of the Absaroka thrust plate, at a depth of about 3 km.^[10]
