Badlands National Park
South Dakota
circa 1970

Badlands National Park is in South Dakota. Its dramatic landscapes span layered rock formations, steep canyons and towering spires. Bison, bighorn sheep and prairie dogs inhabit its sprawling grasslands. The Badlands Loop Road (Highway 240) winds past scenic lookouts. Several trails begin near the Ben Reifel Visitor Center. The Fossil Exhibit Trail is a boardwalk with displays on fossils uncovered in the park.

Badlands National Park (Lakota: Makȟóšiča) is an American national park located in southwestern South Dakota. The park protects 242,756 acres (379.3 sq mi; 982.4 km2) of sharply eroded buttes and pinnacles, along with the largest undisturbed mixed grass prairie in the United States. The National Park Service manages the park, with the South Unit being co-managed with the Oglala Lakota tribe.
The Badlands Wilderness protects 64,144 acres (100.2 sq mi; 259.6 km2) 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 Dance, a former United States Air Force bomb and gunnery range, and Red Shirt Table, the park's highest point at 3,340 feet (1,020 m).
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. Under the Mission 66 plan, the Ben Reifel Visitor Center was constructed for the monument in 1957–58. The park also administers the nearby Minuteman Missile National Historic Site. The movies Dances with Wolves (1990) and Thunderheart (1992) were partially filmed in Badlands National Park.
