About this map

Agricultural development and early aviation infrastructure define this mid-century landscape in Fresno County. At a time when the region's productivity was expanding, the landscape is gridded by a series of named roads including Jeffrey Ave, Cadillac Ave, and Oakland Ave. Large-scale operations like the Diener Ranch and Calflax Ranch anchor the northern sections, while the presence of a Cotton Gin and several Labor Camp sites indicates the labor-intensive nature of the local cotton industry during the 1950s.

The map reveals specialized features such as the Landing Strip, an Airway Beacon, and even a Race Track near Pasajero Farm. These landmarks, along with the Calflax Substation, show the industrialization of the Central Valley floor. A unique margin note from the Geological Survey indicates this entire area lies within a subsidence zone, reflecting the significant groundwater extraction occurring at the time of the survey.
