A massive sculpture of granite rising above the ponderosa pines of the Black Hills of South Dakota, Mount Rushmore National Memorial honors United States presidents George Washington (1st, 1789-1797), Thomas Jefferson (3rd, 1801-1809), Theodore Roosevelt (26th, 1901-1909) and Abraham Lincoln (16th, 1861-1865). Each head is 60 feet (18 m) tall with the entire sculpture clearly visible for many miles from vantage points throughout the Black Hills.
Sculptor Gutzon Borglum, his son Lincoln Borglum, and over 400 workers carved the faces out of the granite over the course of 14 years from 1927 to 1941. Originally designed as a larger sculpture with full upper bodies and greater separation between each president, the enormity of the project, quality of the granite, funding and other issues forced Borglum to scale back the design. Work on the sculpture ended shortly after the senior Borglum's death in 1941.
