Survey the Gold Rush history of the Folsom Lake State Recreation Area using historic and contemporary photographs set side-by-side. State Parks Interpretive Aide Zakary Adams will present Then and Now photos from the same vantage point so you can see the changes in the river and visualize the sunken settlements that are now underneath Folsom Lake. This program is offered in partnership with the California State Parks. Saturday, May 11, 1 p.m. at the Folsom Public Library.
