2018 Map of Humbug Valley

About this map

Lassen National Forest terrain dominates this 2018 survey, where the boundary between Plumas and Tehama counties follows the high ridgelines. The landscape is defined by an intricate network of timber and access roads, including the historic Humboldt Rd and various spurs like Soldier Mdw Spur and Grizzly Creek Spur. The presence of the Pacific Crest National Scenic Trail winding through the northwest corner highlights the area's significance for long-distance transit and recreation. Water resources are central to the geography here, with Big Springs feeding into local drainages and named meadows like Fanani Meadow providing clear markers in the high country. To the south, Little Grizzly Valley and secluded areas like Mudhole Hollow suggest a history of seasonal grazing or quiet mountain habitation away from more developed corridors.
