Badlands National Park

Hundreds of thousands of years ago, this whole area was grassland. Then forces of nature destroyed the grass in some parts. Water and ice cut into the surface of the Earth, splitting open some of its oldest rocks. Nature beat at the rocks, wearing them away.
The result is one of the strangest sights, a place of otherworldly beauty.
All together, the Badlands cover more than 15,000 square kilometers. About 10 percent is part of the national park. The area is a study in extremes. Temperatures in the summer have been as high as 46 degrees Celsius. In the winter they have dropped to as low as 41 degrees below zero.
