问题     Mount Rushmore is a national monument located in the Black Hills of South Dakota. Carved into the side of the large mountain are the faces of four men who were the Presidents of United States.

Thomas Jefferson was added to the right of George Washington, but his face cracked and had to he blasted off the mountain. Jefferson was then re-carved to the left of George Washington. Lincoln and then Roosevelt were added to the mountain.
