Ornbaun Ranch and the Old Ornbaun Hot Springs serve as central landmarks in this mountainous portion of the Mendocino and Sonoma county line during the 1940s. The landscape is defined by a dense network of family-operated holdings, including the Mailliard Ranch, Zeni Ranch, and the Hibbard Ranch, reflecting a period of decentralized rural settlement and livestock operations. The topography is deeply incised by the Garcia River and the North Fork Gualala River, which dictate the placement of roads like the Ornbaun Road. To the east, the small settlement of Yorkville marks a point of connection near the headwaters of Rancheria Creek. Notable for genealogists, this map identifies specific home sites such as the Old Red Rock Place and the Log Cabin Ranch, providing a high-resolution view of land tenure before modern consolidation altered these historic boundaries.
