About this map

The Vallecitos Oil Field and surrounding arid uplands define this mid-century landscape on the border of Fresno and San Benito counties. This survey shows a region deeply invested in natural resource extraction, marked by numerous Oil Wells, a Drill Hole, and multiple mineral Prospects. A series of Pipelines cut across the high ridges of the Panoche Hills and Griswold Hills, illustrating the infrastructure required to transport oil out of these remote canyons.

Water management is captured through features like the Gaging Station on Panoche Creek, a critical point for monitoring runoff in a terrain carved by ephemeral drainages like Silver Creek and Tumey Gulch. The map's detail of Jeep Trails and unnamed access roads reveals the network used by petroleum workers and ranchers to navigate the steep, folded topography of the Ciervo Hills before later 1970s developments.
