This view shows the many towers that carry electricity to light up the Las Vegas Strip and other cities in the West.

When the level of Lake Mead gets too high, it flows around Hoover Dam through diversion tunnels on either side (not spilling over the top of the dam as some might think). The bridge carries US 93 traffic over the spillway on the Arizona side.

This was the highlight of the dam tour. These turbines deep within Hoover Dam use water to create cheap electricity.

I didn't get a photo that showed the entire dam, so this logo will have to do.

These are two of the four intake towers in Lake Mead that deliver water to the power plant at the base of Hoover Dam.

Although more than 100 workers died during the construction of Hoover Dam, the story that some of them are buried within the concrete is a myth. The huge buckets of concrete only filled about three inches in the forms at a time, and the entire dam was not poured continuously (it would have taken too long to set). Also, the workers were very thorough about eliminating air bubbles that would weaken the dam's structure--obviously a human in the midst of the concrete would have weakened the dam as well.

This statue honors the most legendary of the Hoover Dam workers, the high scalers. These men basically swung from ropes along the rock walls drilling holes and planting explosive charges.
