1949 Map of Yorba Linda

About this map

The Olinda Oil Field and extensive Oil Wells dominate this mid-century landscape where the La Puente Hills meet the Santa Ana Mountains. Industrial activity is centered around the settlement of Olinda, while the growing community of Yorba Linda expands along the southern flats. The map documents a critical period of water management and recreation, featuring the Carbon Canyon Mineral Springs and La Vida Mineral Springs tucked into the canyons. Transportation and infrastructure are defined by the Union Pacific and Pacific Electric lines, which serviced both the petroleum industry and the surrounding agricultural citrus groves. To the south, the Santa Ana Canyon serves as a natural corridor for the Imperial Highway, connecting Placentia and Valencia to the broader region.
