About this map

Reef Ridge dominates this mid-1930s landscape, serving as a prominent geological spine between the Kettleman Plain and the high peaks of the Diablo Range. The area reveals a working landscape of ranching and early petroleum infrastructure, evidenced by the Union Oil Co Pumping Sta along the Coalinga-Bakersfield Road. Family-named operations such as the Ernest Kreyenhagen Ranch and Sagaser Ranch are central to the settlement pattern, while the already Jones Ranch (Abandoned) suggests the shifting fortunes of isolated mountain homesteads.
