The Dam is just Huge

This spectacular view of Hoover Dam was taken from near river-level downstream from the huge dam. Here flanked by towering canyon walls, the dam is seen in the distance. Hoover Dam - the highest in the world- was built and is operated by the Bureau of Reclamation of the Department of the Interior.

Dear Everyone:
"We just came through and that is the most beautiful mountain sights I ever expect to see & the dam is just huge. Roads have been good. Sandra had an up set sumach to-day."
Love, Bertha.

At its base, Hoover Dam is 660 feet thick which is 60 feet longer than two football fields laid end-to-end. Combined with its top thickness of 45 feet, there is enough concrete (4.5 million cubic yards) in Hoover Dam to build a two-lane highway from Seattle, Washington to Miami, Florida. Yes, Bertha, that is just huge.
