KEYSTONE, S.D. (AP) — The National Park Service plans to replace lighting at the Mount Rushmore National Memorial.

The agency says there will be no evening lighting on the stone-carved faces of George Washington, Abraham Lincoln, Thomas Jefferson and Theodore Roosevelt from Oct. 6-8 while the work is being done.

The sculpture in the Black Hills of western South Dakota draws nearly 3 million visitors every year.
