About this map

The Temblor Range and Temblor Valley define this landscape on the edge of the San Joaquin Valley, where industrial activity and complex geology meet. By the mid-20th century, the region was heavily shaped by petroleum extraction, as evidenced by the South Belridge Oil Field, the Chico Martinez Oil Field, and the Cymric Oil Field Salt Creek Area. These fields follow the northwest-southeast trend of the terrain, specifically around the McDonald Anticline and the Bacon Hills.

Surface water is sparse, with named sources like Carneros Spring and numerous ephemeral drainages including Chico Martinez Creek and Santos Creek. Beyond the oil derricks, the map records several locations of a Strip Mine and distinctive natural features like Carneros Rocks and Gould Hill. This survey captures the transition from high-elevation ridges to the intensive industrial developments on the valley floor.
