Everyone knows about Mount Rushmore, especially if they have seen Cary Grant and Eve Marie Saint clambering all over it in the climax of North by Northwest.
Located in South Dakota, it is a monument carved out of a granite mountain honouring the first 150 years of US history. It features 18 metre high busts of George Washington, Thomas Jefferson, Theodore Roosevelt and Abraham Lincoln. Carving started in 1927 and concluded in 1941.
