In the spring of 1931, in a rugged desert canyon on the Arizona-Nevada border, an army of workmen began one of the most difficult and daring building projects ever undertaken: the construction of Hoover Dam. Through the worst years of the Great Depression as many as five thousand laborers toiled twenty-four hours a day, seven days a week, to erect the huge structure that would harness the Colorado River and transform the American West.

It’s 1931 - the start of the Great Depression. With jobs running sparse, David Conroy is among the lucky few who is selected to work in the searing heat of the Nevada desert on the massive Hoover Dam, one of America's most amazing and biggest engineering accomplishments. The goal is to tame the mighty Colorado River with a dam that towers sixty stories high. But is the cost too great for these desperate men who must sacrifice their safety to support their families?

The Great Lakes have claimed countless thousands of vessels over the course of history, but its biggest and most famous victim was the SS Edmund Fitzgerald, the largest ship of its day to sail the Great Lakes and still the largest to lie below Lake Superior's murky depths. The giant ore freighter was intentionally built "within a foot of the maximum length allowed for passage through the soon-to-be completed Saint Lawrence Seaway."

Most people have heard of the Seven Wonders of the Ancient World, but while not as many have heard of the Seven Wonders of the Modern World, those who have are aware that the Panama Canal is considered one of them. In a world where few natural rivers carved out over eons of time have reached a length of more than 50 miles, the idea that a group of men could carve a canal of that length seemed impossible. In fact, many thought it could not be done.

The story of the American West is the story of a relentless quest for a precious resource: water. It is a tale of rivers diverted and dammed, of political corruptions and intrigue, of billion-dollar battles over water rights, of ecologic and economic disaster. In Cadillac Desert, Marc Reisner writes of the earliest settlers, lured by the promise of paradise, and of the ruthless tactics employed by Los Angeles politicians and business interests to ensure the city's growth. He documents the bitter rivalry between two government giants to transform the West.
