About this map

Coloma and its surrounding mining claims define the eastern edge of this landscape, situated near the headwaters of Washoe Creek. The settlement is closely tied to its industrial heritage, with concentrated operations at the Coloma Mine, Mammoth Mine, Clemantha Mine, and Cato Mine. The map reveals a high density of extraction sites scattered across the drainages, including the Copper Cliff area and more remote locations like the Comet Mine to the north.

A network of rugged routes such as Garnet Range Rd and Old County Rd connect these sites over the divide to the central watershed of Union Creek. The terrain is marked by deep gulches, such as Klondike Gulch and Bivins Gulch, which feed into major streams like Tenmile Creek. The location of the Coloma Cemetery near Sand Park provides a specific point of interest for those tracing the history of the families who lived and worked in this high-altitude mining district.
