About this map

Coalinga Oil Field operations dominate the northern landscape of this Fresno County survey, where the flatlands of Pleasant Valley meet the rising elevations of the Kreyenhagen Hills. The map documents a mid-century period of heavy petroleum extraction alongside established pastoral ranching. A series of family-held properties, including the Kreyenhagen Ranch, Zuburi Ranch, and Van Dyke Ranch, are situated along the valley floor and foothills, connected by a network of drainage systems like Warthan Creek and Jacalitos Creek.

The rugged terrain south of the oil fields is defined by deep cuts such as Pete Martin Canyon and Deadman Canyon, which transition into the Zapato Hills. Industrial infrastructure is visible through marked pipelines and an Oil Sump, illustrating the resource-driven economy of the era. This edition includes revisions compiled from 1971 aerial photography, showing the evolution of road access along San Joaquin Ave and Alpine Ave into the California interior.
