To wake up with the sun in the middle of the desert - it makes you realize why caravans travel mostly at night. One minute, we are sitting on the bed with the doors open, waiting for the pink sky to light up, the next we are trying desperately to hide from the burning rays of the sun! It gets sooo hot, and sooo quickly! To think that we were using the heater to stay warm not 24 hours ago, too! But we anticipated this heat, this need to shelter from the sun, and so we make our way out of the desert wash, down the road, and to one of the most impressive feats of engineering in US history, the Hoover Dam. If we can't find shade and cooler temperatures deep in the walls of the massive cement structure, then I think we are doomed.

Once upon a time - though only about 15 years ago - the roadway across the dam was the only way to cross the river from Arizona into Nevada and nearby Las Vegas. But it got dangerous, as a "state line" painted on the dam became a popular spot for photos, and cars stopped in the middle of the roadway...Now the line is gone, there is a fancy new bridge built over the canyon which can also accommodate all the cargo trucks, and the only cars crossing the dam are the ones seeking out parking spots! Still, people come in droves to see the marvel, take their pictures, walk over the top and stare down into the bottom of the canyon. But you can also take a tour INSIDE the dam, inside the inspection tunnels and ventilation shafts that help keep the place running and safe?! Yes please!

The sweet coolness of the air-conditioning sweeps over us as we enter the Visitor's Centre, as we pass through obligatory security checks, as we file into a small cinema that bombards us with how great the building of the Hoover Dam was, borderline propaganda(but don't tell anyone I said that). From here, and elevator whisks us down into the heart of the dam, to the pipelines that once diverted the water's flow from the canyon river bed and further downstream, so that work could be done in a dry environment. Now remember that the Hoover Dam was built in the 1930s, often times using mining and drilling equipment frankensteined together with farm equipment, because that's what they had. The pipes used were so large, they could not be shipped by any means available at the time, so a factory had to be created on site to fabricate them! That fact alone puts things into perspective at how big of an undertaking this project was.

Hoover Dam was actually built not for the creation of hydroelectricity, it was built for irrigation control. The rivers here would often flood in the spring - a result of the snow melting in the Rockies and flowing downstream. The communities downstreams would experience horrible flooding conditions every spring, followed by drought later in the year, with no way to balance this out. Hoover Dam would hold back all of that snow melt, creating the largest man-made lake in the US, Lake Mead, but also allowing for the controlled flow of all that water to people who desperately needed it for agriculture and living. But the creation of electricity using the flow of all that water was always part of the plans, and at the base of the dam sit 8 giant turbines, harnessing the power of all that water to help power Las Vegas. Right now, we count ourselves lucky, as some routine maintenance is being done on turbine number 3, and so it has been pulled from its housing and manoeuvred onto the power plant floor in front of us. At 560 tons, it is a great beast, and watching workers pounding at massive bolts holding used magnets in place is captivating. It's fun to see that big machines break in similar ways to small ones, and that sometimes the only solution is a bigger hammer to hit it with.
Next, we enter some of the most interesting places on the tour. Interestingly, the Hoover Dam was always build with tourists in mind, and it shows - the corridors leading from the power plant are clean and tiled, with gorgeous art deco-style aluminum doors and signage for hidden washrooms. Our guide informs us that interest in the dam was peaked from the start of construction, with locals often found lining the edges of the canyons, cheering on their favorite trades' people. So it was normal to include more polished accesses for all of those eventual tourist who would flock from all over the country to see the splendor of the dam. But we get to see further, into the service tunnels, where one of 4 ventilation shafts used to supply fresh air it located. You can see these grates in the vast curved surface of the dam from the observation deck at the Visitor's Centre, and we have fun spotting where we were later on.
We get to walk through some inspection tunnels before heading out. There are over 2 miles of tunnels within the walls of the dam, and though they are lined with electronic sensors and seismographs to repot any anomalies, actually workers will walk those tunnels and perform a visual inspection of the place 2 times a year. They note new cracks in the cement, marking their findings directly on that walls, and so we have fun pinpointing the scribbles and trying to decipher what they might mean. And then we crowd into elevators that whisk us back to the surface, and all that dry heat again. Boo.

So, how do you keep cool when it's 35 C outside and you are in the middle of a desert? You head to the nearest body of water, which, lucky for us, happens to have been made right next to the dam, in the form of Lake Mead. Not only that, but it is a National Recreational Area, with boat launches and picnic areas, and BEACHES, and we jump at the chance to get into the water and cool off. But it is a lake, so the ground is rocky, and mucky, and the water is cooling but not always - it feels good on the skin, and is a welcome break in the middle of the day. We can't do anything else anyways, as hiking would be crazy in the sun. In fact, many of the trails here and in neighbouring parks are closed for the season, on account of the heat, and will reopen only in October. Instead, we drive through the park, ooh-ing and aah-ing at the landscape we pass, layers of rock so distinctly different in colour, it is like driving through a rainbow. And then sometimes it is like driving through a flood of lava, so red and wave-like that it almost seems like waves of the stuff will crash over the road and swallow up the van. In fact, past Lake Mead, we drive through the Valley of Fire State Park, which has less to do with the heat and more to do with the redness of the surrounding scenery.

Sunset finds us just leaving the Valley of Fire and descending to the outskirts of Las Vegas. We won't head completely into town tonight, but stop just short at another of our favorite truck stops. Tomorrow, we return the campervan, and so our evening's activities will consist of eating up the rest of our food supply in the form of a massive cheesy bacon potato pancake, packing up the clothes that seem to have spread their way to all corners of the living space, and attempting to sweep and wipe out a week's worth of dust and dirt from the vehicle. Wish us luck.
