#5 Construction of Mount Rushmore
This memorable photo with the construction of Mount Rushmore was taken in 1939, when there were no machines or advanced technology to help the people carve the perfect sculpture. Made of granite and located in Keystone, South Dakota, Mount Rushmore was the creation of Gutzon Borglum, a Danish-American sculptor and Lincoln Borglum, his son. The work of art features the heads of 4 US presidents – George Washington, Thomas Jefferson , Theodore Roosevelt, and Abraham Lincoln.
