Badlands National Park

[Source]

Badlands National Park is a national park in southwestern South Dakota that protects 242,756 acres (98,240 ha) of sharply eroded buttes, pinnacles, and spires blended with the largest undisturbed mixed grass prairie in the United States. The Stronghold District of Badlands National Park offers more than scenic badlands with spectacular views. Co-managed by the National Park Service and the Oglala Lakota Tribe, this 133,300-acre (53,900 ha) area is steeped in history. Deep draws, high tables and rolling prairie hold the stories of the earliest plains hunters, the paleo-Indians, as well as the present day Lakota Nation. [Wiki]
