1949 Map of Coloma

About this map

Gold Discovery Site State Park and the adjacent James W Marshall State Historic Monument anchor this 1949 survey of the historic heart of California's gold country. The map captures the rugged landscape along the South Fork American River, where the precise Sutters Mill (Site) is identified near the town of Coloma. The terrain is deeply etched by a network of drainage ravines and creeks, including Greenwood Creek and Weber Creek, which provided the water power and access necessary for early mining operations.
