About this map

The geothermal activity of Mayacamas Mountains defines the southern portion of this landscape, where The Geysers (Steam Wells) and a dedicated Power Plant appear alongside the historical Geysers Resort. This industrial footprint extends through a corridor of quicksilver mining, including the Socrates Mine, Culver-Bear Mine, and the settlement of Mercuryville. These sites sit atop the complex drainage systems of Big Sulphur Creek and Little Sulphur Creek, which carve through the high ridges of Geyser Peak and Pocket Peak.

To the north, the terrain transitions into the agricultural Big Valley surrounding Kelseyville. Near the shores of Clear Lake, the map documents the established recreation at Clear Lake State Park and the prominent volcanic landmarks of Mt Konocti and Buckingham Peak. The southwestern corner reveals a different economic engine, where the Northwestern Pacific railroad follows the Russian River through the winery-dotted landscape near Asti. From the resort grounds of Highland Springs to the scattered mercury mines, the map captures a period when natural resource extraction and early geothermal power development operated alongside the region's traditional viticulture.
