About this map

The rugged western edge of the San Joaquin Valley is defined here by the intensive petroleum operations of the Coalinga Oil Field and the Coalinga Oil Field Extension. In this mid-century landscape, oil derricks and extraction infrastructure dominate the terrain south of Anticline Ridge, centering on the small settlement of Oil City. The map documents a critical period of industrial transition, showing how water infrastructure began to reshape the arid landscape.

Large-scale irrigation and transport systems like the California Aqueduct and the Tuolumne Canal cut across the valley floor, contrasting with the remote cattle operations at Domengine Ranch and Jordan Ranch. Between the Big Blue Hills and the valley bottom, features such as the Mack Pumping Sta and various siphons and pipelines illustrate the complex engineering required to sustain both the oil industry and agriculture in this environment.
