Visitors watch while workers wash the faces of George Washington, Thomas Jefferson, Theodore Roosevelt and Abraham Lincoln. The cleaning removes dirt and lichen from the memorial.
National Park Service employee Darin Oestman climbs a rope as he helps pressure-wash Mount Rushmore National Memorial on July 22 in South Dakota. A crew of German workers and National Park Service employees are cleaning the granite faces for the first time in the monument's 65-year history.
Winfried Hagenau, of Germany, bottom, and National Park Service employee Darin Oestman take aim at George Washington's nose. Workers are nearly done with the five-week-long project.
Freshly cleaned faces of South Dakota's Mount Rushmore National Memorial bask in the early morning sun as the moon sets in the distance. The presidential faces received their first cleaning in 65 years as part of a joint project between the National Park Service and the German company Alfred Karcher Co.
Jens Kranhold, of Germany, washes a rough portion of the memorial as the shadow of a co-worker hangs overhead.

German workers Gerhard Buchar, right, and Winfried Hagenau, left, along with National Park Service employee Darin Oestman, clean around the face of Thomas Jefferson.
