Mount Charleston Wilderness is a protected area in southern Nevada that spans the Spring Mountains west of Las Vegas. Established by the U.S. Congress in 1989 under the Wilderness Act of 1964, it is managed by the U.S. Forest Service and the Bureau of Land Management. The wilderness includes Mount Charleston, or Charleston Peak, the range’s highest point, and contains about 18,000 acres of bristlecone pine, the largest such collection in the Intermountain Region of the United States. Its mountain habitat in a desert state supports Clark County’s only herd of Rocky Mountain elk, the endangered Palmer's chipmunk, and about 40 miles of trails.
