St John Mountain dominates this 1968 field-checked landscape at the intersection of Lake, Glenn, and Colusa counties. The terrain is defined by the high ridges and deep canyons of the Mendocino National Forest, where water sources like Sheetiron Spring and Twin Springs provided critical resources for early inhabitants and forest managers. The map records a transition in land use, showing the protected Snow Mountain Wilderness alongside established sites of habitation and recreation.
