The San Carlos Apache Indian Reservation, in southeastern Arizona, United States, was established in 1872 as a reservation for the Chiricahua Apache tribe as well as surrounding Yavapai and Apache bands removed from their original homelands under a strategy devised by General George Crook of setting the various Apache tribes against one another. Once nicknamed "Hell's Forty Acres" during the late 19th century due to poor health and environmental conditions, today's San Carlos Apaches successfully operate a Chamber of Commerce, the Apache Gold and Apache Sky Casinos, a Language Preservation program, a Culture Center, and a Tribal College.
