Hoover Dam

Welcome to one of the greatest engineering feats of the twentieth century. As you stand here, you are currently positioned on the border of Nevada and Arizona, overlooking the deep Black Canyon. Beneath your feet lie over three million cubic yards of concrete, enough to pave a two-lane highway from San Francisco to New York City. This massive structure, rising seven hundred twenty-six feet above the canyon floor, was born during the darkest days of the Great Depression. In nineteen thirty-one, thousands of workers arrived in this harsh desert, where summer temperatures frequently soared above one hundred twenty degrees Fahrenheit, to build a future for the American Southwest. This was not just about concrete and steel; it was about hope. As you look out over the curved face of the dam, notice how it arches into the canyon.^[8] This arch-gravity design uses the weight of the concrete and the natural rock of the canyon walls to hold back the immense pressure of the Colorado River. Take a moment to breathe in the dry desert air and imagine the roar of activity that once filled this quiet canyon as we begin our journey through the history and mystery of Hoover Dam.
