Lassen National Forest dominates the northeast corner of this 2018 survey, where the terrain transitions through high ridges and deeply cut creek forks. The landscape is defined by dramatic geological markers, including the namesake Campbell Mound and the prominent Steamboat Point, which overlooks a complex network of drainages such as Zimmershed Cr and Pine Cr. Historically significant water sources like Negro Spring, Bell Spring, and Root Spring are scattered across the quadrangle, serving as vital points in an otherwise arid and challenging topography.
