About this map

Lassen National Forest and the northern reaches of Lassen Volcanic National Park dominate this 1930s landscape, where the volcanic geology is mapped through features like Cinder Cone, Popcorn Caves, and Caribou Pk. The economy of the High Sierra is evident in the network of remote outposts and family holdings such as the DeLashmutt Ranch, Cone Ranch, and the Russell Dairy. The Western Pacific railroad cuts through the center of the sheet, serving timber and ranching interests in the high valleys.

Logistical hubs and administrative points like the Halls Flat Ranger Sta and Bogard Ranger Sta reflect the early management of these public lands. To the north, the Pit River and Fall River Mills mark a transition toward more established settlements. Geographers can trace the intricate water systems of the volcanic plateau, including Snag Lake, Teal Lake, and the numerous springs like Coyote Spring and Willow Springs that supported the area's isolated mountain camps.
