March Air Force Base occupies the northeastern corner of this Riverside County landscape, illustrating the military's footprint in Southern California during the early 1950s. The map reveals a transition from these institutional grounds to a scattered agricultural and ranching interior, marked by family-named holdings such as the Morris Washington Ranch, Rancho de las Piedras, and Wagonwheel Ranch. This era of development is anchored by the presence of the Colorado River Aqueduct, including both its surface path and the Colorado River Aqueduct Tunnel traversing the southern hills.
