Engineering Marvel of the American West
Hoover Dam is a concrete arch-gravity dam in the Black Canyon of the Colorado River, on the border between Nevada and Arizona. Constructed between 1931 and 1936 during the Great Depression, it was dedicated by President Franklin D. Roosevelt and was the largest dam in the world at the time of its completion.
Our guided tours provide comprehensive access to this engineering masterpiece, including the powerplant, intake towers, and the fascinating history behind its construction. Learn how this massive project tamed the Colorado River and transformed the American Southwest.
Hoover Dam stands 726 feet high and 1,244 feet long, containing enough concrete to build a two-lane highway from San Francisco to New York. Our guides explain the incredible engineering challenges overcome during construction, the worker settlements that became Boulder City, and the dam's crucial role in providing water and power to the growing Southwest.
