Lassen National Forest terrain dominates this high-altitude landscape, where volcanic peaks and seasonally fluctuating wetlands define the local geography. High points like Crater Mtn and Bogard Buttes overlook a series of volcanic flats and valleys, including Grays Valley and Little Round Valley. The hydrography of the region is centered on volcanic basin lakes such as Feather Lake and Long Lake, which feed into the headwaters of the Susan River near Norvell Flat.
