About this map

Mendocino National Forest defines this high-elevation landscape where the boundaries of Lake, Glenn, and Colusa counties converge. Rising to the prominent peak of Saint John Mountain, the terrain is deeply dissected by the headwaters of the Stony Creek system, including the Middle Fork Stony Cr and N Fork Stony Cr. The network of mountain ridges, such as Peavine Ridge and Black Diamond Ridge, suggests a history of timber management and fire lookout access, evidenced by the iconic Ponderosa Way threading through the northern sections.

Settlement is sparse, concentrated at the southern edge near Bonnie View and to the east in Pleasant Valley. These small outposts sit at the threshold of the deep backcountry, connected by historic paths like the Open Ridge-Black Diamond trail. From the high Low Gap to the crossing at Red Bridge, the map documents a geography of remote springs like Sheetiron Spring and Watson Spring, essential markers for early cattlemen and foresters navigating this complex topography.
