Cedar Mountain Wilderness, Wilderness area in northwestern Utah, United States.

Cedar Mountain Wilderness covers more than half of the 180,000-acre Cedar Mountain Herd Management Area in northwestern Utah, just south of Interstate 80. Its upper elevations are dominated by junipers, called cedars by early pioneers, while foothill and valley areas hold mixed desert shrubs and cheatgrass in burned areas. The foothills also contain the remains of an aragonite mining camp.

Congress designated the Cedar Mountain Wilderness at the urging of Utah representative Rob Bishop and the state governor, a move meant to block rail access to a proposed high-level nuclear waste facility on the nearby Skull Valley Indian Reservation. The project, backed by the nuclear power consortium Private Fuel Storage, was abandoned in 2012 after legal obstacles and local opposition.

Herding traditions and grazing practices have shaped how people use this landscape over generations. Local names and stories still reflect early settler misidentifications of the native juniper trees, creating a lasting link to regional identity.

Bring your own water since reliable sources are scarce throughout the area. Navigation across open terrain requires a map and basic orienteering skills, as there are no marked trails or established routes.

A herd of feral horses has roamed this region since the late 1800s, descendants of animals left behind by settlers generations ago. These horses rely on man-made water troughs that are still maintained by land managers today.
