Mendocino National Forest defines the character of this Glenn County landscape, where deep canyons and prominent ridges create a rugged drainage system for Grindstone Creek and Rattlesnake Creek. The settlement of Alder Springs sits as a notable point of human activity along Forest Highway Seven, near the transition to Alder Flat. Further north, Fiddlers Green remains a named locality amidst the high country of Hardin Ridge and Skidmore Ridge. This 2021 survey details an intricate network of remote water sources such as Doe, Bearwallow, and Bathtub, which served as vital landmarks for early forest travelers and ranchers. The map traces the varied terrain from Doe Peak down to the Forks Reservoir, illustrating how the Glenn Co Road (Alder Springs) and the Long Point Trail navigate the complex topography of Sanhedrin Ridge.
