Hoover Dam, once known as Boulder Dam, is a concrete arch-gravity dam in the Black Canyon of the Colorado River, on the border between the U.S. states of Arizona and Nevada. It was constructed between 1931 and 1936 during the Great Depression and was dedicated on September 30, 1935, by President Franklin D. Roosevelt.
The great engineering achievements of the modern world are more than purely functional. The visionaries who dreamed up their imposing shapes used art and science to create structures of dramatic beauty. Our bridges, dams, and skyscrapers, dominate our landscapes, as the pyramids dominated those of ancient Egypt. They're testaments to the creative genius of humankind.
