Mt Sanhedrin dominates the southern landscape of this mid-century survey, anchoring a wilderness of high ridges and deep canyons within the Mendocino National Forest. The Middle Fork Eel River carves a winding path through the north, while the main Eel River defines the southwestern corner near The Island. Settlement is sparse, represented by working outposts like Eden Valley Ranch and Elk Creek Ranch, which were accessible via rugged mountain tracks.
