About this map

The geothermal activity of the Mayacmas Mountains defines the southern portion of this landscape, where The Geysers (Steam Wells) and the Geysers Resort represent a unique intersection of natural energy and early tourism. Further south, the mercury mining legacy of the region is evident through clusters of extraction sites like the Culver-Bear Mine, Buckman Mines, and the Socrates Mine near the settlement of Mercuryville.

In the north, the agricultural expanse of Big Valley centers on the town of Kelseyville, bordered by the volcanic features of Mt Konocit and Buckingham Peak near Soda Bay. The map traces a transition from these fertile flats to the steep ridges of Benson Ridge and Pine Mountain. Transportation and local infrastructure are marked by the Northwestern Pacific railroad corridor along the Russian River and aviation facilities such as Lampson Airport, showing the mid-century development of Lake and Sonoma counties.
