The Cedar Mountain Wilderness is located in northwestern Utah, United States, just south of Interstate 80.

A survey conducted in December 1991 counted 444 horses, and parts of the herd can often be seen on the wilderness.

The Bureau of Land Management fills watering troughs for the horses when springs dry up in the summer.

The U.S. Congress designated the Cedar Mountain Wilderness, in an effort sponsored by Utah representative Rob Bishop and the Utah governor, to block rail access to a proposed high-level nuclear waste storage facility on the nearby Skull Valley Indian Reservation.

The project was sponsored by a consortium of nuclear power companies known as Private Fuel Storage.
