About this map

Lassen National Forest dominates this section of the northern Sierra Nevada, where the high-altitude landscape is defined by volcanic features and timber management. The prominent Blacks Mtn rises above a complex of drainage and storage systems including Busters Reservoir and Railroad Reservoir. This terrain, primarily utilized for seasonal grazing and forest service operations, is marked by specific working sites such as Beaver Creek Pasture and Blacks Cabin Flat.

A network of forest service routes, including the Hat Ck/Lit Valley Tie (Dr 22), provides access through the deeply eroded Blacks Gulch. Evidence of the area's utility is seen at Puls Camp, while natural water sources like Gibbs Spring and Blacks Lake support the local ecosystem. The map captures the specialized geography of a working national forest, where the names of springs and ridges trace the history of regional land use.
