Mount Rushmore National Memorial: Nearly three million visitors a year come to marvel at the majestic beauty of the Black Hills of South Dakota and to learn about the birth, growth, development and the preservation of the USA through the largest piece of public art on the planet. Badlands National Park: Formed by the geologic forces of deposition and erosion leaving striking geologic deposits containing one of the world's richest fossil beds. 244,000 acres of sharply eroded buttes, pinnacles and spires surrounded by a mixed-grass prairie ecosystem.

While bison, elk, and prairie dogs enjoy the prairie, below, this complex labyrinth of passages contains a unique formation, boxwork. Jewel Cave National Monument: The third longest cave in the world, with over 168 miles of mapped and surveyed passages, this underground wilderness reveals fragile formations with glimpses of brilliant color.
