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 approximately 2 million people annually.Known to the Lakota Sioux as Six Grandfathers, the mountain was renamed after Charles E. Rushmore, a prominent New York lawyer, during an expedition in 1885. At first, the project of carving Rushmore was undertaken to increase 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 with a few injuries and no deaths.
Sculptor Gutzon Borglum began drilling into the 5,725-foot mountain in 1927, at the age of 60.
Creation of the Shrine of Democracy took 14 years and cost a mere $1 million.
Rushmore's granite faces tower 5,500 feet above sea level.
The carvings on Mount Rushmore are scaled to men who would stand 465 feet tall.
