About this map

Lassen Mountain and the deep canyons of the North Fork Feather River dominate this 1948 landscape, capturing a moment of industrial activity and mountain settlement within the Plumas National Forest. The Western Pacific railroad tracks hug the river's contours, serving remote outposts like Las Plumas and Berry Creek Station. The presence of the Diversion Dam, a Tram, and a Powerhouse near Island Bar reflects the river's development for utility during this era.

Legacy mining operations are scattered across the slopes of Big Bend Mountain, including the Evening Star Mine and the Treasure Hill Mine. Local life is anchored by small community landmarks like the Berry Creek Sch and the Rockefeller Sch. Names like Rose Ranch and New Blinzig point to established homesteads and settlements connected by rugged mountain roads before later 20th-century developments altered the region.
