About this map

The South Fork American River cuts a deep path through this Gold Country landscape, centering on the historic site of the 1848 discovery that sparked the California Gold Rush. The community of Coloma is preserved in part by the Gold Discovery Site State Park, which marks the Sutters Mill (Site) and the James W Marshall State Historical Monument. Surrounding this central hub are the settlements of Lotus and Uniontown, connected by roads that wind through steep ravines like Norton Ravine.

Resource extraction remains visible in the hills, with the Lilyama Mine to the north and the Boulder Mine and Delores Mine tucked near Weber Creek in the south. The terrain is defined by prominent peaks including Mt Ararat and Clark Mtn. Along with several cemeteries and the Springvale School, the map documents a transition from an intensive mining district to a region shaped by historical preservation and rural residence by the mid-20th century.
