About this map

Lassen National Forest dominates this section of the Sierra Nevada mountains, where high-altitude peaks and vital water sources define the local geography. Significant elevations like Roop Mountain and Fredonyer Butte anchor the high ground, while the Hog Flat Reservoir and Big Spring indicate the critical role of water management and natural springs in this arid timberland. The map provides a detailed view of the drainage patterns for the Susan River and its tributaries, such as Willard Cr.

Resource access and land management are visible through the network of specialized forest roads and spurs, including Quarry Spur and Harry Gul Spur. These routes, alongside named terrain features like Goat Mtn and Crazy Harry Gulch, reflect the area's history of logging, ranching, and backcountry utility. The survey illustrates the complex boundary lines between national forest tracks and public land sections, traceble through the numerous numbered sections across the quadrangle.
