1950 Map of Portola

About this map

Portola serves as the central hub of this mid-century Sierra Nevada survey, situated where the Western Pacific Railroad follows the path of the Middle Fork Feather River. The landscape transitions from the high peaks of Crocker Mountain and Dixie Mtn down into the broad, flat expanse of the Sierra Valley to the southeast. This survey captures a specific moment in the regional economy, showing the Logging Railroad extending north into Dixie Valley and the Plumas County Airport established near Beckwourth. Rural life is marked by sites such as the Ramelli Ranch, the Island Sch (Aband), and Marble Hot Sprs. The map also delineates the extensive boundaries of the Plumas National Forest and the State Game Refuge, highlighting the early 1950s balance between industrial rail activity and forest conservation.
