About this map

The Dunnigan Hills dominate the western portion of this mid-century landscape, characterized by a series of north-south ridges that give way to the agricultural flatlands of the Sacramento Valley. The settlement of Zamora sits at the intersection of local roads and the Southern Pacific railroad line, serving as a hub for the surrounding ranching and farming operations. The map highlights the early energy infrastructure of the region, specifically the Dunnigan Gas Field, where several Gas Wells are marked across the undulating terrain.

Water management is central to this environment, evidenced by the Colusa Basin Drainage Canal and the Colusa Basin boundary to the northeast. Seasonal drainages such as Oat Creek, Bird Creek, and Willow Creek cut through the hills, feeding into the lower valleys. Other local landmarks like Oat Valley and Hungry Hollow provide specific geographic context for researchers and genealogists tracing land use and property history in Yolo County.
