Mormon Island reappears -- a Gold Rush settlement that once held 2,500 people, built on a 300-foot sandbar where members of the Mormon Battalion found gold in the American River. By the 1940s, fire, depleted claims, and a new railroad had emptied the town. In 1953, the government bought the land, and Folsom Lake swallowed what remained. Two million visitors come to Folsom Lake State Recreation Area each year. Most of them have no idea they are boating over the bones of a town that gold built and water erased.
