The Sierra Diablo WMA, 11,624 acres, is named for and located in the mountain range extending north and south along the Hudspeth and Culberson county line. The Area was acquired by Texas Parks and Wildlife in 1945 to serve as a sanctuary for the last remaining desert bighorn sheep in Texas. The Area is currently utilized for the restoration, conservation, and management of bighorn sheep and is home to the largest free-ranging population in Texas. As such, caution must be used while hunting for other species. The WMA has a well established and stable desert mule deer population. Rough rugged hills and steep canyons make up the area which is reached from the southwest across gently, sloping foothills. After attaining an average elevation of 6,200 feet, the topography breaks sharply with 1,000 foot drops to the desert floor to the east.
