About this map

Lassen Volcanic National Park dominates the northern reaches of this mid-century survey, showcasing a geothermal landscape where Boiling Springs Lake and the active vents of Bumpass Hell meet high-altitude waters like Juniper Lake and Summit Lake. The map reveals a specialized recreation and ranching economy, from the established resort atmosphere at Drakesbad and Warner Valley Springs to the more utilitarian Stump Ranch and Feather River Rod & Gun Club.

Transport and land use patterns are defined by the intersection of four counties—Shasta, Plumas, Tehama, and Lassen—and a network of trails and jeep roads that connect remote outposts like Kelly Camp and Lee Camp. Significant infrastructure of the era, such as the Radio transmitter (KMA 498) near Stover Mountain, stands alongside natural curiosities like the Ice Cave on Ice Cave Mountain, illustrating the mid-1950s transition toward modern forest management and expanded public access in the High Sierra.
