Elk Mountain was a resting spot, the Elk Mountain Station, for early American pioneers in wagon trains heading west on the Overland Trail. Heading west, the travelers came from the Rock Creek Overland Stage Station. The Stage Station and the pioneers selected the site because of the good water year-round from the Medicine Bow River. There are many willow and cottonwood trees. It was also used as a route for the Overland Stage and Mail from 1862 to 1869, which ran from Denver to Salt Lake. From Elk Mountain, travelers moved west on the Overland Trail to Fort Halleck.
The post office was established in 1877. The town was incorporated in 1909.
