Badlands National Park, located in Interior South Dakota, is the location of the world’s largest fossil beds. The 244,000 acre park is home to sedimentary rock layers deposited over 70 million years ago, as well as mixed grass prairie where bison, bighorn sheep, prairie dogs, and ferrets live. There are over 60 species of grass throughout the prairies inside the park. Named by the early French trappers and the Lakota Native American tribe that founded the area, the Badlands are known for extremes: extreme weather, extreme vastness of the plains, and extreme fossil beds.

Badlands became a National Monument in 1939 and then a National Park in 1978; the southern half of the park is located on the Pine Ridge Indian Reservation and is co-managed with the Oglala Sioux Tribe. Over one million people visit Badlands National Park each year.
