Mount Rushmore National Memorial is more than a sculpture carved into the side of Mount Rushmore in the Black Hills of South Dakota, USA. It's more than a depiction of four American Presidents -- George Washington, Thomas Jefferson, Theodore Roosevelt, and Abraham Lincoln -- who represent the first 130 years of American history.
This is a story of an idea brought to life by Americans willing to put their lives on the line to create a grand memorial. It's also a monument with secrets, from ties to white supremacy and the KKK, to a secret chamber located in the stone. Check out the images as we dig into this great American landmark.
