1987 Map of Coalinga

About this map

The Diablo Range and the San Andreas Rift Zone dominate this section of Central California, where the rugged terrain of Peachtree Valley and Priest Valley meets the industrial footprint of the San Joaquin Valley. In the late 1980s, the economic landscape was defined by the extensive Coalinga Oil Field, Pleasant Valley Oil Field, and Jacalitos Oil Field flanking the city of Coalinga. This geography highlights the intersection of intensive petroleum extraction and large-scale water management, evidenced by the California Aqueduct and Coalinga Canal cutting through the arid Kettleman Plain.
