Sculptor Gutzon Borglum created the sculpture's design and oversaw the project's execution from 1927 to 1941 with the help of his son, Lincoln Borglum . Mount Rushmore features 60 - foot (18 m) sculptures of the heads of four United States presidents: George Washington (1732--1799), Thomas Jefferson (1743--1826), Theodore Roosevelt (1858--1919), and Abraham Lincoln (1809--1865). The memorial park covers 1,278.45 acres (2.00 sq mi; 5.17 km) and is 5,725 feet (1,745 m) above sea level . </P> <P> South Dakota historian Doane Robinson is credited with conceiving the idea of carving the likenesses of famous people into the Black Hills region of South Dakota in order to promote tourism in the region . Robinson's initial idea was to sculpt the Needles; however, Gutzon Borglum rejected the Needles because of the poor quality of the granite and strong opposition from Native American groups . They settled on Mount Rushmore, which also has the advantage of facing southeast for maximum sun exposure . Robinson wanted it to feature American West heroes like Lewis and Clark, Red Cloud, and Buffalo Bill Cody, but Borglum decided the sculpture should have broader appeal and chose the four presidents . </P>
