About this map

The South Fork American River carves a deep valley through this El Dorado County landscape, centered on the foundational site of the California Gold Rush. In the village of Coloma, the Gold Discovery Site State Park and Sutters Mill (Site) represent the 1848 discovery that transformed the American West. Just south, the James W Marshall State Historical Monument stands on a ridge overlooking the river and the settlement of Lotus.

Beyond the historic riverfront, the terrain is marked by early industrial activity and local infrastructure. Active and legacy mining operations like the Lilyama Mine, Boulder Mine, and Delores Mine are scattered across the hills. Local genealogists will find value in rural landmarks such as the Johntown Cem, the Springvale School, and the junction at Four Corners, providing a clear picture of the community's mid-century footprint near Thompson Hill and Gold Hill.
