We decided to get out of Las Vegas and after a very meagre Travelodge brekkie, we set off for the Hoover Dam. It was quite close near Boulder, the town that was built to house the workers building the dam. After a false turn that took us to the Boulder golf club we found our way to the dam. It had a large multi-level car park and well organised guides to take you through the dam.

The Hoover dam was named after President Hoover who sponsored the dam to control flooding and provide water for irrigation and electric power. It was built in the 1930's and employed 1000s of men over 6 years. The first task was to tunnel through the walls of the canyon to provide diversion for the Colorado river. These four tunnels were 50ft in diameter to cope with the river flow and were later used for spillway and penstocks. Many men died in the tunnels and they took years to complete. Then the dam started. It is a gravity arch concrete dam which is 100m deep at the base and 15m deep at the crest and 220m high with 6 million tonnes of concrete. They developed a chilling plant to pump cold water through the fresh concrete to keep it cool and allow faster pouring rates.Our tour took us down to the diversion tunnels and then to one of the power stations.
