1941 Map of Mineral

About this map

Lassen Volcanic National Park and the sprawling Lassen National Forest dominate this landscape during the mid-1930s survey period. The transition from the Sacramento Valley floor into the high volcanic reaches is marked by early hydroelectric developments at Volta Power House and Inskip Power House. Settlers and surveyors have left a dense network of family-named landmarks and seasonal outposts across the terrain, including the Facht Homestead, Brockman Cabin, and Apperson Place.
