About this map

Lassen National Forest terrain dominates this 1980 survey, characterized by prominent volcanic peaks and a complex network of high-altitude water sources. High points like Roop Mountain, Worley Mtn, and Fredonyer Butte define the topography, while the Susan River flows through the southern portion of the quadrangle. The map reveals a landscape managed for both preservation and utility, evidenced by the proximity of the Hog Flat Reservoir to various working sites.

Local ranching and resource extraction are clearly visible through features like the Barrell Ranch, Willard Ranch, and Sunan. Notable landmarks such as Devils Corral and Crazy Harry Gulch offer specific points of interest for those tracing the historical geography of Lassen County. Numerous water sources, including Beartrap Spring and Big Spring, highlight the essential natural resources that supported these early settlements and forest management activities.
