In the middle of the Black Hills of South Dakota lies one of the greatest US treasures: Mount Rushmore. Carved between the years of 1927 and 1941 by Danish-American Gutzon Borglum and his son, Lincoln. Mount Rushmore features 60 foot high sculptures of four former US Presidents: George Washington (1732-1799), Thomas Jefferson (1743-1826), Theodore Roosevelt (1858-1919) and Abraham Lincoln (1809-1865).
