Mount Rushmore’s peak is 5,725 feet above sea level. Scientists predict the sculpture will erode 1 inch every 10,000 years. The park site regularly draws over 2 million visitors annually.

Mount Rushmore was sculpted between October 4, 1927, and October 31, 1941. Sculptor Gutzon Borglum and 400 workers sculpted the presidents to represent the first 150 years of American History.

South Dakota Gov. Larry Rhoden invited Trump to visit Mount Rushmore to celebrate the country's 250th birthday for Independence Day next year, according to a news release from his office.
