The land is sacred to Native Americans from the San Carlos Apache Indian Reservation and many other Arizona tribes. This federally-managed area is listed on the National Register of Historic Places, and features a National Forest Service public campground. The landscape includes Apache Leap cliff, the mesa of Oak Flat, and Devil's Canyon, all of which have long been popular with hikers, birders, climbers, off-roaders, hunters, and members of the area's indigenous tribes. Oak Flat has been subject to attempts by the federal government to exchange the site for lands owned by mining interests since 2002, against the wishes of the San Carlos Apache tribe.
