The White Rim Road is a 71.2-mile-long (114.6 km) unpaved four-wheel drive road that traverses the top of the White Rim Sandstone formation below the Island in the Sky mesa of Canyonlands National Park in southern Utah in the United States. The road was constructed in the 1950s by the Atomic Energy Commission to provide access for individual prospectors intent on mining uranium deposits for use in nuclear weapons production during the Cold War. Large deposits had been found in similar areas within the region; however, the mines along the White Rim Road produced very little uranium and all the mines were abandoned.
