About this map

Sutters Mill (Site) and the Gold Discovery Site State Park anchor this map of the historic heart of California's gold country. Situated along the South Fork American River, the area around Coloma and Lotus is depicted just after the post-war field checks of the late 1940s. The landscape is a network of gold-rush history, preserved through the James W Marshall State Historical Monument and various lode deposits like the Lilyama Mine and Boulder Mine.

Beyond the river, the topography rises toward Mt Ararat and Thompson Hill, where a more rural, agricultural pattern emerges at Four Corners and Gold Hill. Notable local landmarks include the Springvale School and the Uniontown Cem near the settlement of Uniontown. The intricate drainage system, featuring Greenwood Creek and Weber Creek, underscores the geographic complexity that both aided and challenged early mining operations in El Dorado County.
