Badlands National Park encompasses 244,000 acres of striking Badlands formations – steep canyons, jagged spires, bands of colorful rocks – blended with mixed-grass prairie.  Created by 37 million years of wind and water erosion, the Badlands’ formations feature ribbons of colored stone embedded with the remains of prehistoric creatures.  This land, one of the most famous of the world’s “badlands”, was once home to three-toed horses, giant pigs and rhinoceros-like titanotheres.
