The Big Blue Hills define the western landscape of this Fresno County region, where the steep terrain of Ragged Valley and Sulphur Flat meets the industrial reach of the California oil industry. By the mid-1950s, the East Coalinga Extension Oil Field and the Coalinga Anticline Ridge were established hubs of extraction, marked by a dense network of pipelines and pumping infrastructure like the Mack Pumping Sta. This 1971 revision documents the introduction of the California Aqueduct, which cuts diagonally across the valley floor, contrasting the newer water infrastructure with the established ranching life at Domengine Ranch and Jordan Ranch. The map captures a specific moment when agricultural operations such as Sunset Farms operated alongside the massive engineering projects designed to move water and oil across the San Joaquin Valley.
