2018 Map of Coloma

About this map

The South Fork American River carves a central path through this landscape, defining the historic settlements of Coloma and Lotus. As the site of the first gold discovery in California, this area retains deep connections to its mining heritage, evidenced by the James Marshall Monument Grave and multiple burial grounds including Uniontown Cem and Pioneer Cem. The terrain is characterized by significant elevations such as Mt Ararat and Clark Mtn, while the southern reaches descend toward Gold Hill. Aviation and recreation are integrated into the modern rural character, with the Bacchi Valley Industries Airport and the extensive Cronan Ranch Road network providing access to the river's edge. The map reveals a transition from the riparian corridor of Granite Canyon to the residential and agricultural stretches along Marshall Rd and Lotus Rd.
