Hoover Dam is really an amazing technological wonder. It was built during the 1930’s to dam the Colorado River to provide water for the southwestern United States. If you visit, I recommend taking time for the “dam tour”. It is pretty neat inside. One of the things I found most interesting was that they built a pipe factory onsite just to build the giant pipes for the water to flow through since they would be to large to ship there. I hope you enjoy the pictures. rk
