1960 Map of Ornbaun Valley

USGS Topo · Published 1962

About this map

Ornbaun Valley and the Anderson Valley serve as focal points for this remote landscape, where Mendocino and Sonoma counties meet. In the early 1960s, the terrain was defined by a series of prominent ridges, including German Ridge, Phelps Ridge, and Rockpile Ridge, which channeled the many forks of the Gualala River and Garcia River. The map reveals a land utilized for both recreation and large-scale ranching, featuring the Mailliard Ranch and the Helvetian Gun Club. A network of specialized openings, such as the Little Horse Opening and Mule Opening, suggests a history of livestock management or forest clearing. Notable landmarks for local researchers include the Ornbaun Sprs Cem and the Gualala Mtn Lookout, alongside the preserved groves of Mailliard Redwoods State Park.
