The construction of Mount Rushmore, a United States National Monument depicting the heads of four U.S. Presidents carved into the Black Hills of South Dakota, began on August 10, 1927, with the bust of George Washington. This first phase was completed in seven years (partial completion in 1932 shown here), culminating in its unveiling in 1934. The remaining three heads—Thomas Jefferson, Abraham Lincoln, and Theodore Roosevelt—took only an additional seven years to complete.Photo credit: Rise Studio
