History of Uinta County
Uinta County was created on December 1, 1869. This happened when the government of the Wyoming Territory decided to form it. Its first temporary main city was Fort Bridger.

When it was first made, Uinta County covered the entire western edge of Wyoming. This even included the area where Yellowstone National Park is now. The county got its name from the Uinta Mountains in Utah. You can see these mountains from many places in the county. Uinta County got its current shape in 1911. This was when Lincoln County was created from its northern part.

Geology and Land Features
The western part of North America has a wide area of folded and pushed-up rock layers. This area stretches from Alaska all the way to Mexico. In southwest Wyoming, including Uinta County, this process created several long faults. These faults formed over millions of years, from the Late Jurassic to the early Eocene periods.
One important discovery happened in 1977 at the Painter Reservoir Field. Oil was found in a thick layer of sandstone. This sandstone forms a special trap for oil, about 3 kilometers deep underground.
