Throughout the Cold War, the United States tested atomic weapons in the Nevada desert about 125 miles north of Las Vegas. Not only were the mushroom clouds from those tests visible from the Las Vegas strip, they also became an unlikely tourist attraction.

The book weaves together primary documents, photos and the stories of residents, scientists and soldiers. NewsHour Weekend's Ivette Feliciano reports.
