1959 Map of Mount St. Helena

About this map

Mount St Helena dominates the eastern horizon of this 1959 landscape, standing at the meeting point of Sonoma, Lake, and Napa counties. The rugged terrain of the Mayacmas Mountains is marked by a legacy of mercury and mineral extraction, evidenced by clusters of workings such as the Chicago Mine, Helen Mine, and the Western Mine. In the lower elevations to the southwest, Knights Valley provides a contrast with more accessible terrain, where the settlement of Kellogg and a local Cem are situated along the path of Maacama Creek. This survey captures a specific era of California's back-country infrastructure, including a Fish Hatchery in Tanbark Canyon and various remote outposts like Locke Cabin. The map details the complex drainage patterns of the region, from the headwaters of Big Sulphur Creek to the winding course of Redwood Creek.
