The two units of Theodore Roosevelt National Park encompass 70,000 acres of rugged Badlands. Inside the park, near Amidon, is an area where burning underground coal beds emit an intense heat through a fissure in the earth's surface. Prehistoric plant and animal fossils, as well as several petrified forests, are found at this location. Buttes, domes, and cones that resisted erosion rise up on both sides of the Little Missouri River. Mineral deposits cause these rock towers to cast hues of lavender, green, yellow, and red.
