About this map

Los Banos is the central hub of this post-war San Joaquin Valley landscape, showcasing an intricate network of irrigation and transportation that defined mid-century Merced County. The grid-patterned town is flanked by the Airport and the small settlement of Abatto to the east. Agriculture dominates the terrain, evidenced by the dense web of waterways including the Main Canal, Arroyo Canal, and Mercy Canal, which redirected water across the arid flats. The map captures a moment when rail was still vital, featuring the Southern Pacific and Santa Fe lines cutting diagonally through the territory. To the northeast, the landscape shifts toward the marshy San Jon de Santa Rita and the winding course of Mud Slough, where the Los Banos Gun Club stands near the Delta West Drain. This survey documents the intersection of large-scale engineering and local ranching life, punctuated by numerous Windmills dotting the valley floor.
