Mount Rushmore National Memorial, near Keystone, South Dakota, is a monumental granite sculpture by Gutzon Borglum (1867–1941), located within the United States Presidential Memorial. It consists of 18m sculptures of the heads of former United States presidents (left to right): George Washington (1732–1799), Thomas Jefferson (1743–1826), Theodore Roosevelt (1858–1919), and Abraham Lincoln (1809–1865). Originally 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. The memorial was created in order to increase tourism to the Black hills region of South Dakota. It attracts approximately two million visitors every year.
