Badlands, South Dakota:

Deep canyons, towering spires, and flat-topped tables can all be found among Badlands buttes. Located on the edge of our country’s Great Plains, its part of the largest undisturbed mixed prairie rangeland remaining in the United States. Within the park’s 244,000 acres is the Badlands Wilderness, 64,000 acres of pristine National Wilderness where you can see bighorn sheep, coyotes, black-footed ferret, swift fox, bison and mule deer. The  rolling sea-of grass that surrounds Badlands is one of  the largest grasslands—known as Buffalo Gap National Grasslands—which is the home of the largest free roaming mammal of the US: the American bison. This is a heritage area with a long ancestry that traces its history from prehistoric hunters and gatherers to today’s tribes of the Great Sioux Nation, and later homesteaders, ranchers, and farmers.
