About this map

Huron and the agricultural lands of the San Joaquin Valley meet the rising terrain of the Kettleman Hills in this 1940s survey. The landscape is defined by the transition from the flat valley floor, marked by a precise grid of roads like Eldorado Avenue and Lassen Avenue, to the intricate drainages carving through Anticline Ridge. The Southern Pacific railroad cuts a diagonal line across the plains, serving as the primary corridor for the region's ranching economy.

Several family-named operations anchor the territory, including the Pleasant Valley Ranch, Zubeldia Ranch, and Kreyenhagen Ranch. The topography becomes significantly more complex south of The Washboard, where numerous arroyos such as Arroyo Zapato and Arroyo Hondo snake through the hills. This era shows Avenal as a burgeoning center at the southern edge of the sheet, situated near the Fresno-Kings county boundary.
