Hoover Dam is a concrete arch-gravity dam in the Black Canyon of the Colorado River. It is strategically located to hold such massive amount of water flow between the canyons of Arizona and Nevada.
A few meters walk will send you to a totally different time zone. The penstock towers' wall clocks, standing on each state's side, will show the time difference. During winter and autumn, the time difference is one hour. So, if it's 9am in Nevada (Pacific Standard Time), it's 10am in Arizona (Mountain Standard Time). During spring, since Arizona does not observe Daylight Saving Time, the two states will have no time difference. Weird and fascinating at the same time.
Marvel at this engineering genius and see how more than 100 died to make the desert bloom.
