1967 Map of Ontario

About this map

Ontario and its neighboring citrus and aviation hubs are shown during a period of significant urban expansion across the Inland Empire. The landscape is defined by a dense grid of residential and commercial growth, yet traces of its agricultural and early industrial roots remain visible in place names like Sunsweet and the historic Santa Ana Del Chino land grant. This era highlights the area's role as a major transportation nexus, where the Southern Pacific, Union Pacific, and Atchison Topeka and Santa Fe railroads converge near the growing Ontario International Airport. Educational and community anchors like the Chaffey High Sch and the Botanic Garden in Claremont stand alongside established neighborhoods in Upland and Montclair. The map captures the transition of the San Bernardino Valley from a decentralized collection of towns into a connected metropolitan corridor.
