About this map

The Middle Fork Feather River carves through the heart of this Plumas County landscape, following a corridor shared by the Western Pacific railroad. The settlement of Portola serves as a central hub, while the nearby community of Beckwourth sits at the edge of the wide Sierra Valley floor. This 1950 field-checked survey reveals an era of transition in land use, noting the Ramelli Ranch (Abandoned) and Island Sch (Aband) alongside active infrastructure like the Plumas County Airport.

High-altitude landmarks such as Beckwourth Peak and Crocker Mountain overlook a complex network of canyons and flats, including Grasshopper Flat and Dotta Canyon. The map details specialized land management through the Dixie Mountain State Game Refuge and the borders of the Plumas National Forest and Tahoe National Forest. From the Marble Hot Sprs to various logging railroads, the map preserves the mid-century industrial and natural character of the Feather River country.
