The United States Congress designated the Fortification Range Wilderness (map
) in 2004 and it now has a total of 30,539 acres
All of this wilderness is located in Nevada
and is managed by the Bureau of Land Management.
The 13.5 mile long Fortification Range is a low mountain range composed almost entirely of volcanic materials (tuffs and tuffaceous breccia). Most of the range is comprised of gentle ridges, however, the north end becomes very rugged and precipitous (elevations range from 6,150 to 8,268 feet) where the rock has been eroded into sheer cliffs and massive outcrops. These spectacular formations and cliffs for which the range was named form a huge natural amphitheater at the head of the Cottonwood Canyon drainage. Scattered ponderosa pine, pinyon, juniper, aspen and cottonwood are found in the northern portion of the wilderness, while the southern portion is densely forested by pinyon and juniper. Wildlife within the wilderness includes mule deer, antelope, mountain lions, and raptors.
