The Santa Ana River cuts a wide swath across this landscape, separating the growing urban centers of Anaheim and Santa Ana from the rugged canyons to the northeast. During the early 1940s, the region was a patchwork of expanding grid-patterned towns and vast agricultural tracts, interconnected by an extensive rail network including the Pacific Electric, Union Pacific, and Southern Pacific. The presence of the Los Angeles Air Base and small worker settlements like Colonia Manzanillo reflect the wartime industrial and social character of the county.
