FILE - In this May 2,1933, file photo shows the carved face of U.S. president George Washington on Mt. Rushmore, in South Dakota. The last living worker who helped construct Mount Rushmore National Memorial in South Dakota's Black Hills has died. Donald "Nick" Clifford of Keystone, South Dakota, was 98. His wife, Carolyn Clifford, says he died Saturday at a hospice in Rapid City. At 17, Clifford was the youngest worker hired to work at Mount Rushmore. He operated a winch that carried workers up and down the mountain where the faces of Presidents George Washington, Thomas Jefferson, Theodore Roosevelt and Abraham Lincoln were carved, and he drilled holes for dynamite.
