Badlands National Park is one of the most underrated parks in North America, covering over 240,000 acres of land, 64,000 of which are protected as a designated wilderness area. The park is home to hundreds of species of wildlife, including the American Bison, Black-Footed Ferrets (an endangered species in North America), and Big Horn Sheep. Native Americans who inhabited the area gave the park its name, as they described the land using this adjective due to the extreme temperatures, drought, and tough land. The Badlands and its highly recognizable scenery with incredible rocky formations of steep buttes and pinnacles became a National Park in 1978.
