About this map

Reef Ridge dominates this mid-1930s landscape at the intersection of Kings, Fresno, and Monterey counties, where high ridges and deep canyons reveal an era of early industrial and ranching activity. The northern section is marked by the Kreyenhagen Hills and the Ernest Kreyenhagen Ranch, while the Kettleman Plain to the east shows early petroleum infrastructure, notably the Union Oil Co Pumping Sta along the Coalinga-Bakersfield Road.

Mineral extraction and rural subsistence are evident through the Dawson Mine and several isolated outposts like the Jones Ranch (Abandoned) and Sogaser Ranch. The complex topography, including Avenal Ridge and peaks such as Garza Peak and Tar Peak, is punctuated by essential water sources like Willow Spring and the curiously named The Turtle Hole. This survey captures a specific moment when heavy industry began to penetrate these remote ranching corridors.
