About this map

Lassen National Forest terrain dominates this mid-1990s survey, illustrating a landscape defined by the drainage systems of Humbug Valley and the high ridges of the Sierra Nevada. The historical Humboldt Road cuts through the territory, marking a traditional route through the mountains that predates modern highway development. The map details a complex network of water features, from the large meadow of Soldier Meadows to smaller alpine features like Mud Lake.

Tracing the path of the Pacific Crest National Scenic Trail along Ruffa Ridge, the map identifies scattered family-named outposts such as Baccala Ranch and Lemm Ranch. These ranching sites, situated near Big Springs and Yellow Creek, provide evidence of the long-standing livestock and water-management history in this part of Plumas County. The border between Tehama and Plumas counties follows the natural drainage divides, showcasing the rugged intersection of high-country topography and political boundaries.
