Mount Rushmore

The Mount Rushmore National Memorial is a national memorial centered on a colossal sculpture carved into the granite face of Mount Rushmore in the Black Hills near Keystone, South Dakota, United States. Sculptor Gutzon Borglum designed the sculpture, called Shrine of Democracy, and oversaw the project's execution from 1927 to 1941 with the help of his son, Lincoln Borglum. The sculpture features the 60-foot-tall heads of four United States presidents: George Washington, Thomas Jefferson, Theodore Roosevelt, and Abraham Lincoln, chosen to represent the nation's birth, growth, development, and preservation, respectively. Mount Rushmore attracts more than two million visitors annually to the memorial park which covers 1,278 acres. The mountain's elevation is 5,725 feet above sea level.

The sculptor chose Mount Rushmore in part because it faces southeast for maximum sun exposure. The carving was the idea of Doane Robinson, a historian for the state of South Dakota.
