Aldo Leopold Wilderness, along with Gila Wilderness and Blue Range Wilderness, is part of New Mexico's Gila National Forest. It became part of the National Wilderness Preservation System in 1980 by an act of the United States Congress and has a total of 202,016 acres (81,753 ha).[1] The wilderness area lies along the crest of the Black Range.
The Continental Divide of the Americas traverses parts of the wilderness.

The area with the Aldo Leopold Wilderness was formerly part of the Gila Wilderness, the world's first Wilderness Area, established in 1924. Later, the Gila was reduced in size and this area became the Black Range Primitive Area. In 1980, the Aldo Leopold Wilderness was created, named after Aldo Leopold, a pioneering environmentalist.
The Aldo Leopold Wilderness area stretches north-south along the crest of the Black Range for about 30 miles (50km) and has a maximum width of about 15 miles (25km). The elevation of the crest ranges from 8,600 feet (2,622 mts) to 10,165 feet (3,099 mts) at McKnight Mountain, the highest point in the Wilderness area. The crest of the range overlooks a series of east-west trending steep and narrow stream valleys, one thousand or more feet deep. The lowest elevation in the Wilderness area is about 6,000 feet (1,829mts).[2]
Vegetation in the Aldo Leopold consists of a Spruce-Fir and Quaking Aspen forest above 9,000 feet (2,732mts), Ponderosa Pine forest between 6,500 feet (1,981 mts) and 9,000 feet (2,732 mts) and Pinyon-Juniper woodland and desert vegetation below 6,500 feet and on dry southern slopes. Due to the prevalence of forest fires in the Wilderness area, brushy areas, grassland, and recently-burned forests are also common. Hardwood forests, especially Cottonwood, line many of the larger streams. [3]
The Wilderness area has fauna typical of the American Southwest: Mule deer, Elk, Wild Turkey, Peccary, Black bear and Cougar. Of note is the effort to reintroduce the Mexican wolf to the region. The native Gila Trout has been brought back from the verge of extinction and now exists in small populations in Diamond Creek, South Diamond Creek and Black Canyon on the west side of the Black Range. A population of Rio Grande Cutthroat trout survives in Holden Prong of Las Animas Creek on the east side of the Black Range. [4] The Mimbres River has its headwaters in the Wilderness.
Aldo Leopold is rugged and remote and is often considered New Mexico's "wildest wilderness," probably seeing fewer human visitors in 2011 than it did 100 years ago. Hiking and backpacking are the major recreational activities, but scarcity of water inhibits many potential visitors. Most streams and springs are seasonal and unreliable. More than 200 miles of trails crisscross the Wilderness, including about 30 miles of the Continental Divide Trail.[5] Most trails are faint and little used and navigation can be a problem. Scenery and solitude are the main attractions of the Aldo Leopold Wilderness. Hunting is permitted.
The best known and most accessible trail into the Wilderness leads from Highway 152 at 8228-foot (2508 m) Emory Pass and goes five miles north to Hillsboro Peak which reaches an elevation of 10,011 feet (3,051 m). This trail continues to follow the entire north-south length of the mountains along the central ridge, a distance of 51.4 miles from Emory Pass to Caledonia trailhead on New Mexico 226. There are also a number of campgrounds, some with hiking trails, along NM 152 as it goes through Iron Canyon on the west side of the range.[6]
