Mount Rushmore KÄRCHER co-operated with the National Park Service to clean the presidents’ heads on Mount Rushmore in South Dakota (USA). The restorative cleaning work was carried out as part of a culture sponsoring project. The aim was to remove lichen, algae, moss and other organic stains that could damage the underlying rock in the long term by way of corrosion.
The first cleaning project on Mount Rushmore started on Independence Day, July 4, 2005, and was completed in early August.
Sculptor Gutzon Borglum’s giant heads of American Presidents George Washington, Thomas Jefferson, Theodore Roosevelt and Abraham Lincoln were carved between 1927 and 1941. They are about 60 ft (18-meters) high and, along with the Statue of Liberty in New York, probably the best known monument in the United States. It is located near Rapid City in South Dakota and is managed by the National Park Service, together with the museums and other facilities
