The Fortification Range Wilderness protects the 13.5-mile (21.7 km) long Fortification Range, a low mountain range composed almost entirely of volcanic materials. Most of the range is gentle ridges, though the north end is very rugged and precipitous and contains sheer cliffs and massive outcrops.[2]
A variety of vegetation grows in the Fortification Range Wilderness, including ponderosa pine, pinyon pine, juniper, aspen, and cottonwood trees in the northern portion of the Wilderness. The southern portion is densely forested with pinyon and juniper. Common wildlife found the Wilderness includes mule deer, antelope, mountain lion, and various raptors.[2]
Popular recreational activities in the Fortification Range Wilderness include hiking, camping, backpacking, photography, nature study, horseback riding, fishing and hunting.[2]
