This park's sharply textured rock formations share a 244,000-acre landscape with the largest protected mixed-grass prairie in the United States. The buttes, pinnacles and spires that define this region have been eroding for half a million years into their distinctive shapes — and continue to erode at a rate of about an inch per year. The park's rugged beauty attracts visitors from around the world, and its geologic deposits contain the world's richest Oligocene epoch fossil beds, estimated at 23 to 35 million years old. Badlands National Park is also an excellent place to see the night sky; on any given night, visitors may see up to 7,500 stars and a particularly clear view of the Milky Way.
