Hoover Dam
Hoover Dam is huge. It is 726 feet high and more than 1,200 wide at the top. Two of the small towers at the top are restrooms with Art Deco motif.
This was taken from the top of the dam. If you look very carefully, there is a tiny blue car on the pier. The larger dark spot on the pier was a tour group and the voice of the guide could be heard from where I took this picture.
