About this map

Potter Valley and the surrounding Mendocino County highlands define this mid-century landscape, where a complex network of ranching, water management, and Indigenous lands intersect. The map documents the Pomo Indian Reservation and the Redwood Valley Indian Reservation, while also detailing the irrigation infrastructure of the era, including the Potter Valley Irrigation Canal, Cape Horn Dam, and the Van Arsdale Reservoir.

A distinct cluster of named ranches and seasonal retreats suggests the region's mid-century character, from the Emandale Resort and Hertstone Inn to family-held properties like Triangle G Ranch and the Mewhinney Ranch. Transportation is anchored by the Northwestern Pacific railroad in the southwest, while the Ridge Trail and various unimproved roads navigate the transitions between the valley floor and the high peaks of the Mendocino National Forest.
