Northeast of Hummingbird Springs, which sits near the middle of this Wilderness, a colorful escarpment, Sugarloaf Mountain, climbs steeply from the Tonopah Desert to 3,418 feet and lends this area remarkable scenic value. Over eight miles of the Big Horn Mountains are included in this Wilderness. Here you'll find hills and washes and bajadas abounding with saguaro, ocotillo, cholla, paloverde, and mesquite, habitat for desert bighorn sheep, mule deer, and desert tortoise. Kit foxes and Gila monsters race along the ground while Cooper's hawks, prairie falcons, and golden eagles rule the skies. Without maintained trails, the area can be backpacked easily, and primitive campsites abound. The water from Hummingbird Springs runs into a catchment accessible via a non-Wilderness jeep trail slicing into the area from the southern boundary. This jeep trail is all that separates Hummingbird Springs Wilderness from Big Horn Mountains Wilderness to the south.
