1956 Map of Oxalis

About this map

The San Joaquin River defines the northeastern boundary of this landscape, which in the mid-1950s was characterized by a sophisticated network of irrigation and drainage infrastructure. Centered on the community of Dos Palos, the map illustrates how water management shaped the local economy and settlement patterns, with the Delta-Mendota Canal and Outside Canal cutting through the terrain. The presence of the Southern Pacific railroad line, passing through Oxalis, provided the critical transport link for agricultural goods.
