Mount Rushmore National Memorial, near Keystone, South Dakota, is a United States Presidential Memorial that represents the first 150 years of the history of the United States of America with the 60-foot (18 m) sculptures of former U.S. Presidents George Washington, Thomas Jefferson, Theodore Roosevelt, and Abraham Lincoln. The entire memorial covers 1,278 acres (5.17 km²), and is 5,725 feet (1,745 m) above sea level. It is managed by the National Park Service, a bureau of the United States Department of the Interior. The memorial attracts around 2 million people annually.

The mountain known to the Lakota Sioux as Six Grandfathers was renamed after Charles E. Rushmore, a prominent New York lawyer, in 1885. The project of carving Mount Rushmore originally started with the purpose of increasing tourism in the Black Hills region of South Dakota. After long negotiations involving a Congressional delegation and President Calvin Coolidge, the project received Congressional approval. The carving started in 1927 and ended in 1941, and although there were a few injuries, no deaths occurred.
