Hoover Dam was America's shining light during the dark days of the Great Depression. This monumental structure was the largest federal works project of its time, constructed after years of scientific study and political maneuvering by California boosters. This thirsty state looked to the untapped Colorado River to supply reliable water for Imperial Valley farms and the fast-growing Los Angeles metropolitan area. Harnessing the unruly Colorado River would be no easy task. Only the federal government could fulfill the dream. An unprecedented high dam, over 700 feet tall, was designed to store two years of river flow, trap tons of silt, and gain control of the river. The project was financed by the sale of hydroelectric power to southern California, Arizona, and southern Nevada. Today, Imperial Valley is an American garden spot, and Los Angeles is one of the nation's most influential cities. The Las Vegas Valley also witnessed tremendous growth beginning with the dam and followed by legalized gambling, defense industries, and tourism. Meanwhile, the small town of Boulder City, born during the dam's construction, still thrives in the shadow of Hoover Dam.

Area 51, a top secret military installation for testing unacknowledged, or black, projects, lies in a desert valley northwest of Las Vegas. During the Cold War, CIA and Air Force officials chose this remote location to shield such efforts from foreign spies and US citizens. Although the base has been known by many names—Paradise Ranch, Watertown, and Dreamland, among others—the designation Area 51 has taken root most deeply in the public imagination. Since 1955, it has grown from a temporary camp into a national test facility supporting nearly 2,000 military and civilian workers and dozens of projects, including aircraft capable of cruising at Mach 3 and stealth airplanes that are virtually invisible to radar. Although secrecy surrounding Area 51 spawned rumors of UFOs and reverse-engineered alien spacecraft, declassified photographs provide a rare glimpse into the true nature of America's most famous secret base.

There was a time when Goldfield, Nevada, was known around the world as a city growing in the desert, seemingly out of nowhere, with no natural resources except for the extremely rich and plentiful mineral found in the ground--gold! In England, they were afraid the amount of gold mined in Goldfield would flood the market, making gold worthless. In Germany, gold seekers heard of the riches and made their way to the remote desert site. Those that had gone to Alaska for the great Klondike rush were now headed to Nevada. Goldfield was the last great gold rush on the American frontier. Discovered in 1902, its boom lasted about a decade and then came the inevitable and fateful decline. Yet its story is largely unknown. Nevada historians and scholars have documented Goldfield for years; others have amassed vast collections of ephemera, artifacts, and photographs; and some have even collected and restored the town's most impressive buildings. Through personal photo albums and accounts of those who were there, this book reflects life in Goldfield, Nevada, the last great American gold rush.

During the midst of the Great Depression, Boulder City came to life due to the Boulder Dam project, which offered people a path of hope. This wonderful town's heritage does not end at its buildings or sites, for they are just the icing to a richer culture. Standing in present time with images of their past will allow those in the community or newcomers a fresh view on the preservation efforts and care that Boulder City represents.
