The United States Congress designated the Delamar Mountains Wilderness (map
) in 2004 and it now has a total of 111,066 acres
All of this wilderness is located in Nevada
and is managed by the Bureau of Land Management.
Several deep, twisting canyons issue from the central core region and into the southern bajada. The eastern mountainous region holds hills, peaks, washes and draws. Many of the canyon areas and some of the boundary zones have spectacular cliffs.
This area provides steep, rugged terrain for desert bighorn sheep and a variety of raptors. The long sloping bajadas around the periphery of the wilderness provides critical habitat for the threatened desert tortoise. The Delamar Mountains Wilderness encompasses a portion of the Mormon Mesa Desert Tortoise Area of Critical Environmental Concern. Sensitive species likely to be found in the wilderness area include the white bearpoppy and banded Gila monster.
