In the heart of the Black Hills of South Dakota, the busts of George Washington, Thomas Jefferson, Theodore Roosevelt, and Abraham Lincoln stand as one of the most patriotic symbols of the United States. The Mount Rushmore National Memorial is a sculpture carved into the granite face of Mount Rushmore near Keystone, South Dakota, in the United States. Sculpted by Danish-American Gutzon Borglum and his son, Lincoln Borglum, Mount Rushmore features 60-foot (18 m) sculptures of the heads of former United States presidents (in order from left to right) George Washington, Thomas Jefferson, Theodore Roosevelt and Abraham Lincoln. The entire memorial covers 1,278.45 acres (5.17 km2) and is 5,725 feet (1,745 m) above sea level. The tallest mountain in the region is Harney Peak (7,242 feet or 2,207 metres).
