The United States Congress designated the Beaver Dam Mountains Wilderness (map
) in 1984 and it now has a total of 18,667 acres
It is managed by the Bureau of Land Management.
The jagged mountains and gently sloping alluvial plain of Beaver Dam Mountains Wilderness straddle the Arizona-Utah border. Management of the Wilderness is shared by the BLM in both states. It is further divided into northeastern and southwestern units by Cedar Pockets Road. South of Beaver Dam lies Paiute Wilderness, which is separated from Beaver Dam Mountains Wilderness by the corridor of Interstate 15
Joshua trees, desert shrubs, and scattered grasses are the primary vegetation. Several rare plant species have also been identified here. Notable wildlife include desert bighorn sheep, the endangered desert tortoise, and large numbers of raptors. The woundfin minnow and Virgin River chub, endangered species, live in the Virgin River, which flows through the eastern section of Beaver Dam Mountains Wilderness for approximately 6 miles. River rafters and kayakers have been increasingly attracted to the Virgin River, but water levels can be too low for this form of travel in the fall and winter. Spring runoff and summer thunderstorms can create whitewater rafting and kayaking experiences in this area. Backpacking in the Wilderness has seen a substantial increase in recent years. There are no trails, so hone your cross-country skills before heading out.
