About this map

Mendocino National Forest encompasses this high-elevation interior landscape, dominated by a series of prominent northwest-trending spines such as Thatcher Ridge and Etsel Ridge. The drainage patterns are defined by the Middle Fork Eel River at the western edge and various mountain creeks, including Mississippi Cr and Thatcher Cr, which carve deep canyons into the terrain.

Evidence of human habitation and seasonal use appears at the Barnes Ranch and identified locales like Haynes Flat and Hand Flat. The map documents a landscape characterized by distinct geological landmarks, from the singular Chimney Rock to the remote waters of Skunk Lake. The network of ridges, including Camp Meeting Ridge and Horse Pasture Ridge, suggests a history of livestock grazing and traditional travel routes through these northern California mountains.
