The Hoover Dam. It is AWESOME!!!
The water it holds up is called Lake Mead and is the largest man made lake.
What we did was go on a tour inside the dam and see the power plant. The part of the power plant we saw had 10 generators. One small generator only generated part of the power for the Hoover Dam lights and was completely rusted. The whole dam capacity is just over two million kilowatts of power. A normal electric room heater uses about two kilowatts, so the Hoover Dam could run one million electrical room heaters. After that part of the tour, we walked down a long underwater, underground hallway and every time you said something it echoed back at you. After we got to the end of the long hallway there was a vent. This vent was on the non-wet side of the dam. I stuck my hand out of the vent.
After the tour we found lots of coins under the feet of a statue. I made about one dollar in coins. Also before the tour we saw a big hole that also echoed back at us. The big hole was the overflow chamber for the water. It helped them build the dam.
There is a bridge nearby that gives a great view of the dam and you can be in two states at one time.
We had a great day. If you go, take the long dam tour.
