American Experience - Season 14 Episode 6 Mount Rushmore

Chronicling the 16-year struggle (1925-41) to fashion Mount Rushmore in South Dakota's Black Hills, and profiling sculptor Gutzon Borglum, its creator. Borglum was 60 when plans for Rushmore were announced and he died not long after the final busts were completed. In between, money was often scarce and the granite from which the likenesses were hewn was crumbly. But Borglum wouldn't be denied, and he had foresight: He planned for 300,000 years' worth of weather erosion.
