About this map

Industrial infrastructure and ranching life define this Fresno County landscape during the mid-1930s. The Southern Pacific railroad cuts through the terrain, serving as a vital transport link for the region's burgeoning energy sector, most notably represented by the massive Oil Tank Farm and the Caliola Pumping Sta. These facilities mark a significant period of petroleum development in Central California, situated just east of the prominent Kreyenhagen Ridge.

Away from the industrial sites, the map details the rural character of the valley floor, where Pleasant Valley Ranch and the small stop at Turk anchor the local community. The seasonal hydrology of the area is evident in the paths of Arroyo Pasajero and Zapato Creek, which drain toward the Polvadero Gap. This 1:31,680 scale survey provides a clear view of the intersection between early 20th-century agriculture and the infrastructure of the oil industry along Jayne Avenue.
