1941 Map of Folsom

About this map

The State Prison at Represa overlooks the confluence of the North Fork American River and the South Fork American River in this 1940s landscape. Long before the modern reservoir altered the topography, the American River corridor was defined by gold-rush era sites and early valley settlements like Folsom and Natoma. The map reveals an intricate network of water management and transport, featuring the Natomas Ditch and the Southern Pacific railroad line snaking through the foothills.
