Mount Rushmore is one of the country's most famous monuments. Officially dubbed the Mount Rushmore National Memorial, the sculpture is an astounding sight because of its size, its detail and its surroundings. Each year, 3 million visitors come to take snapshots of the likenesses of Presidents Washington, Jefferson, Roosevelt and Lincoln. Yes, this mammoth sculpture is impressive, but equally impressive from a nature-lover's perspective, is the landscape of the surrounding area. The Black Hills of South Dakota contain forests and unusual rock formation, and the region is also home to the Badlands, the famously stark land that sits adjacent to the Black Hills.
