The Dorr Ranch represents the inherent difficulties faced by homesteaders who attempted to ranch in the arid areas of eastern Wyoming. William and Mabel Dorr established the Dorr Ranch in 1915.

The Dorrs primarily raised horses and cattle during their tenure at the ranch. During their ownership of the property the Dorrs experienced a series of financial hardships until they sold the property in 1928. The main house continued to be occupied until 1949. Buildings and structures remaining on the site include the main house, two log cabins, stable, windmill, cistern, and the remains of a schoolhouse.
