Mendocino National Forest defines the character of this 2018 survey, which documents a landscape of dramatic verticality where the Eel River and its tributaries carve through the northern California backcountry. High peaks and expansive ridgelines like Kneecap Ridge, Bear Wallow Ridge, and Gibson Ridge dominate the terrain, illustrating the complex watershed system feeding Spanish Cr and Corbin Cr. The area is marked by distinctive natural landmarks such as The Basin and Gravelly Flat, alongside localized points of interest like Cold Spring. This topographic record provides an essential look at the remote interior of Lake and Glenn counties, tracing the network of forest routes including the Glenn Co Road and the Kneecap Cabbage Patch trail, which offer passage through the steep drainages and mountain summits of the Coastal Range.
