Hoover Dam Tour
This incredible dam was constructed during the Great Depression and was dedicated on September 30, 1935 by President Franklin Roosevelt. Originally called the Boulder Dam it was built between 1931 and 1936 in the Black Canyon on the state line between Nevada and Arizona. This was a huge project involving thousands of workers who were on the clock for 24 hours a day. Over a hundred people died during the construction. The dam was named after President Herbert Hoover at a later date causing some controversy.
