About this map

The South Fork American River flows through this gold country landscape, centering on the ground where the California Gold Rush began. The historical weight of the region is evident in the inclusion of the Sutters Mill (Site) and the Gold Discovery Site State Park, along with the James W Marshall State Historical Monument. The settlements of Coloma and Lotus are surrounded by a terrain defined by steep ridges like Mt Ararat and Clark Mtn, while the Uniontown Cem preserves a record of the early community near the riverbanks.

Industrial activity and early education are visible through the marking of the Lilyama Mine, Boulder Mine, and the Springvale School. The map tracks numerous creeks such as Greenwood Creek, Rock Creek, and Weber Creek, illustrating the complex drainage systems that once supported mining operations. Changes added in the 1970s, like a Landing Strip and road updates, show the area's gradual transition from its mid-century state.
