Learn about the building of Hoover Dam, a working monument to ingenuity and will power that forever changed the face of America.

Rising more than 700 feet above the raging waters of the Colorado River, it was called one of the greatest engineering works in history. The Hoover Dam, built during the Great Depression, drew men desperate for work to a remote and rugged canyon near Las Vegas. There they struggled against heat, choking dust and perilous heights to build a colossus of concrete that brought electricity and water to millions and transformed the American Southwest.
