1960 Map of Ornbaun Valley

About this map

Ornbaun Valley serves as a central point in this study of the Mendocino and Sonoma county borders, where rugged mountain ridges and ranching properties dominate the landscape. The map details a complex network of ridgelines, including German Ridge, Signal Ridge, and Yellow Hound Ridge, which divide the drainages of the Garcia River and the Gualala River. Local land use is characterized by named ranch holdings like the Mailliard Ranch and Rickard Ranch, alongside specialized clearings such as Beebe Opening and Cox Opening. Conservation and recreation are represented by the Mailliard Redwoods State Park and the Helvetian Gun Club. Genealogists may find interest in the Ornbaun Sprs Cem, while surveyors can trace the precise boundary line between Mendocino and Sonoma County as it traverses over Rockpile Peak.
