Hoover Dam, Nevada

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 Arizona and Nevada. When completed in 1936, it was both the world's largest hydroelectric power generating station and the world's largest concrete structure. It was surpassed in both these respects by the Grand Coulee Dam in 1945. It is currently the world's 38th-largest hydroelectric generating station

We took the dam tour which went into the power house. It was awesome to see these huge turbines working. At one point inside the dam your standing over one of the intake tubes, which moves water to the turbines at 100,000 gallons a second, the floor rumbles and vibrates from the pressure.

This is the new bridge being built to bypass the dam, your running out of time if you want to drive across it. You will still be able to park and walk out, just not drive.

The white line around the lake “bath tub ring” is how high the water gets. When the water levels go down the minerals from the water deposit in the surrounding walls.
