Lassen National Forest dominates the southern half of this landscape, where the terrain rises toward the volcanic peak of Coble Mountain. This 1990s revision reveals a region defined by high-elevation springs and drainage systems, with Beaver Creek and the Pit River carving through the northeastern corner. The boundary between Shasta and Lassen counties cuts vertically through the center, marking a transition from the volcanic features of the west, such as Cinder Cone and the nearby Cinder Pit, to the grazing lands around Burton Ranch. The network of 4wd roads and trails illustrates how this remote timber and range land was managed in the late twentieth century. Researchers can trace historic water sources like Willow Spring, Compton Spring, and Canyon Spring, which provided essential resources across Sheep Flat and the surrounding volcanic rim.
