Hoover Dam and Lake Mead Recreation area

We spent a good 6 hours on our first day of the trip to Las Vegas area at Hoover Dam and the Lake Mead recreation area. Our original plan was to go see Bryce canyon or Grand canyon. A blizzard ruled out those plans. The decision was to see what we could within a two hour radius of our hotel. 

San and me have seen the dam and lake as well as west Grand Canyon on a mini plane tour from Henderson when we were newly married! That was ages ago and we don't even have a way to replay those mini VHS tapes these days!  This was our chance to see the dam, up close and personal.

So we went on the "dam" tour!

This tour takes more than an hour and is twice as expensive as the regular tour but totally worth it. 

Lake Mead is behind this 750 foot tall 600+ foot wide monstrosity! If you see the larger version of the pic by clicking it you will see four shield shaped markings on the concrete.. 

You can see one of them on the center of the picture above. It is actually one of four air vents that balances the air inside the dam so that the concrete cures. Concrete takes years to cure. This one is to cure in 125 years. So they keep monitoring the moisture content and curing rate of the concrete from inside the dam. 

Concrete sets in an exothermic reaction. The designers of the dam used special steel tubes to vent the heat from the setting concrete to cool it down while building the dam. Otherwise there was no way it was built that fast. They had a refridgeration plant cool down the concrete through these tubes while pouring blocks of concrete 5-6 foot tall at one time.. 

You go through these nicely finished tunnels to reach one of the four air vents on the tunnel.

This is the view of the end of the air vent from the inside.

and that is what you see when you look out of the vent. A mighty Colorado river that runs in a very controlled way out of the dam!

After seeing the view from the vent, we also got to see the staircase that runs up and down the dam as an emergency exit in those days. 

We also saw the turbine room. There are these LARGE turbines each weighing more than 600 tons that generate electricity. 

There is also a smaller generator that is on the ground that supplies power to the dam itself. The scale of this building and everything in it is simply mind blowing. 

Once the water comes out of the turbines, it exits down through the gates. You can see that in picture below.

 The dam's mid point is the state border between Nevada and Arizona. So the kids had fun magically moving through two time zones and being in two timezones at the same time.. The older kids understood my idea of trying to a collage showing them in two zones and posed for me, but my execution was flawed.. Should have taken more wider angle shots to merge.. 

We spent another hour wandering around the exhibits and the statues of the two angels and drove on to the Lake Mead Recreation area to have lunch. 

It was very scenic spot (stitched shot below)

Will definitely recommend this as a day trip activity for the entire family. If you have really small kids under 3 would not recommend it. The Dam tour can be pretty claustrophobic. 

The parking lot, restrooms, exhibits etc. were world class! Everyone enjoyed it. The kids learned a thing or two about of hydro electric power is generated using stators and rotors and that was really cool. 

We did not know what to expect when we hit the parking lot, but we came out after having a great time!
