Which mountain is carved with the faces of four U.S. presidents?

Mount Rushmore is the mountain carved with the faces of four U.S. presidents.

The colossal sculpture is in the Black Hills of South Dakota, near Keystone. Its 18-metre presidential heads depict George Washington, Thomas Jefferson, Theodore Roosevelt and Abraham Lincoln. Sculptor Gutzon Borglum and his workers carved the memorial between 1927 and 1941, using the granite face of Mount Rushmore.

The four presidents were chosen to symbolize different stages of U.S. history: the nation's founding, expansion, development and preservation. South Dakota historian Doane Robinson originally proposed a sculpture honoring figures from the American West, but Borglum persuaded organizers to create a national monument instead.

Mount Rushmore is the mountain and the sculpture's name is formally Mount Rushmore National Memorial. It is often mixed up with the Crazy Horse Memorial, another enormous Black Hills carving that remains unfinished and honors the Lakota leader Crazy Horse. Mount Vernon, by contrast, is George Washington's historic estate in Virginia.
