High on a granite cliff in South Dakota's Black Hills tower four huge carved faces of American presidents. But is Mount Rushmore a monstrosity, or a masterpiece? A temperamental artist, Gutzon Borglum, propelled the project by sheer talent and guts, even as his ego and obsession threatened to tear it apart. Relive the hucksterism and hyperbole of his massive public works project during the Great Depression. Narrated by Michael Murphy.
