1930 Map of Avenal Gap

About this map

The Kettleman Hills and Kettleman Hills (South Dome) dominate this 1930 topographic study, capturing a critical landscape in the San Joaquin Valley just as the region's oil potential was being heavily explored. The settlement at Devils Den and the nearby Devils Den Sch represent the sparse human footprint in this arid terrain, located near the junction of the Coalinga Bakersfield Road and the Antelope Plain. The map provides a detailed view of the natural topography of Avenal Gap and the Kettleman Plain, marking the administrative boundary between King Co and Kern Co. This area is characterized by its complex folding and geological significance, which defined the economic development of Central California during the early 20th century. The inclusion of the Pyramid Hills and the Lamoore Road further illustrates the primary transportation corridors connecting these remote oil and ranching districts.
