Badlands National Park boasts one of the largest mammal fossil deposits in the world! Park visitors can even join in the fossil hunting fun. Badlands has an open hike policy, so you are not required to stay on designated trails! This policy, rare in a national park, actually encourages visitors to go off trail to search for fossils. As a result, every year photos of park visitors and their fossil finds are added to the wall of fame in the Badlands National Park visitor center.
