Badland

   Badlands National Park is an American national park located in southwestern South Dakota. The park protects 242,756 acres of sharply eroded buttes and pinnacles, along with the largest undisturbed mixed grass prairie in the United States. The Badlands Wilderness protects 64,144 acres of the park's North Unit as a designated Wilderness Area, and is one site where the black-footed ferret, one of the most endangered mammals in the world, was reintroduced to the wild. The South Unit, or Stronghold District,  includes sites of 1890s Ghost Dancers, a former United States Air Force bomb and gunnery range, and Red Shirt Table, the park's highest point at 3,340 feet. Authorized as Badlands National Monument on March 4, 1929, it was not established until January 25, 1939. Badlands was redesignated a national park on November 10, 1978.
