About this map

Blocksburg serves as a central hub in this mid-century look at the southern Humboldt County mountains, where isolated ranches and forest camps define the social landscape. The rugged topography is divided by the Van Duzen River and the Mad River, with the Northwestern Pacific railroad cutting through the canyon of the Eel River at Eel Rock. This survey records a network of family-held land such as the Bosworth and Windbigler Ranch, alongside specialized operations like the Snowline Fox Farm.

High elevation features like Mt. Lassic (Signal Pk) and the Lassic Lookout underscore the region's importance for forest management within the Six Rivers National Forest. From the Buck Mtn School to remote outposts like Coffee Pot Summit Camp, the map documents a transition era where traditional ranching and the timber economy met increasing recreational use at sites like the Van Duzen Public Camp.
