About this map

Portola serves as the primary hub of this Plumas County landscape, situated where the Western Pacific railroad tracks trace the course of the Middle Fork Feather River. The settlement pattern in the early 1970s is concentrated around the river valley, with the adjacent community of Delleker and the village of Beckwourth to the east. Local history is anchored by the Shady Grove Cem and Whispering Pines Cem, alongside the local High Sch.

The surrounding terrain is dominated by the steep rises of the Plumas National Forest, including heights like Beckwourth Peak and Crocker Mountain. To the north, State Game Refuge 1-V occupies the high ground above Big Grizzly Creek. Evidence of earlier infrastructure is visible in the Old RR Grade winding through the hills, while the vast Sierra Valley opens up to the southeast, characterized by the Sierra Valley Channels.
