The Middle Fork Feather River carves through this mountain landscape, serving as the central corridor for the city of Portola and the nearby settlement of Delleker. This 1994 revision highlights a region defined by the complex boundary between the Plumas National Forest and the Tahoe National Forest, where high-elevation landmarks like Beckwourth Peak and Crocker Mountain overlook the broad expanse of the Sierra Valley to the east. The map records important local genealogy sites, including Shady Grove Cem, and social markers such as the High Sch and Whispering Pines. Notable infrastructure includes the Feather River Scenic Byway and various forest management features like the State Game Refuge 1-V and the Beckwourth area, providing a clear picture of land use in the northern Sierra Nevada during the late twentieth century.
