Water streaks down the faces of presidents George Washington, left, and Thomas Jefferson, center, as workers pressure wash Mount Rushmore National Memorial in South Dakota July 22, 2005. Workers were in the midst of a five-week-long project to clean dirt and lichen from the presidential faces. President Abraham Lincoln is at far right. The granite sculptures hadn't been washed since they were completed 65 years ago by sculptor Gutzon Borglum. (KEYSTONE/AP Photo/Charlie Riedel)
