About this map

Guijarral Hills and the adjacent Anticline Ridge dominate the landscape of this mid-century Central Valley survey. The region is defined by its industrial petroleum infrastructure, featuring the sprawling East Coalinga Oil Field Extension and the Coalinga Oil Field. Numerous oil wells, tanks, and sumps are scattered across the valley floor, linked by an extensive grid of service roads including Tornado Avenue and Phelps Avenue.

Settlement patterns reflect a mix of worker-focused infrastructure and rural estates, from the Labor Camp and Caliola Pumping Station to the Pleasant Valley Ranch. The Southern Pacific railroad line cuts through the center of the quadrangle near the small community of Turk, following the natural drainage of Los Gatos Creek. A notable recreation site, the Polvadero Country Club, sits near the southern edge, providing a sharp contrast to the surrounding oil-rich industrial landscape of Pleasant Valley.
