South Dakota

A stone's throw from the Black Hills, Jewel Cave National Monument is home to the third longest cave in the world. The Badlands boast 30 million-year-old fossil beds, 1500 free roaming bison live in Custer State Park, and Mount Rushmore took 14 years to build. Those are some big numbers for a state you may not have given a second thought to. Spend a season exploring the Coyote State!
