Located in southwestern South Dakota, Badlands National Park consists of nearly 244,000 acres of sharply eroded buttes, pinnacles and spires blended with the largest, protected mixed grass prairie in the United States. Sixty-four thousand acres are designated official wilderness. Sage Creek Wilderness is the site of the reintroduction of the black-footed ferret, the most endangered land mammal in North America. The Stronghold Unit is co-managed with the Oglala Sioux Tribe and includes the sites of 1890’s Ghost Dances.

Established as Badlands National Monument in 1939, the area was redesignated as a National Park in 1978. Over 11,000 years of human history pales to the eons old paleontological resources. Badlands National Park contains the world’s richest Oligocene epoch fossil beds, dating 23 to 35 million years old.
The evolution of mammal species such as the horse, sheep, rhinoceros and pig can be studied in the Badlands formations.
