Mendocino National Forest defines this high-elevation landscape on the border of Lake and Glenn counties. The topography is dominated by a series of prominent ridges, including Kneecap Ridge, Bear Wallow Ridge, and Spanish Ridge, which separate the headwaters of numerous creeks. Drainage patterns here are complex, with Black Butte River and the Eel River carving through the western sections of the map.
