Mount Rushmore.

The story of Mount Rushmore's creation is as bizarre and wonderful as the monument itself. It is the tale of a hyperactive, temperamental artist whose talent and determination propelled the project, even as his ego and obsession threatened to tear it apart. It is the story of hucksterism and hyperbole, of a massive public works project in the midst of an economic depression. And it is the story of dozens of ordinary Americans who suddenly found themselves suspended high on a cliff face with drills and hammers as a Danish sculptor they considered insane directed them in the creation what some would call a monstrosity, and others a masterpiece.
