1954 Map of Ontario

USGS Topo · Published 1955

About this map

Pomona College and the surrounding academic landscape of Claremont anchor the northern portion of this mid-century survey, a period when the inland valley was transitioning from its citrus-growing roots into a dense suburban and industrial corridor. The map captures the institutional growth of the era, including Scripps College and the newly relocated Rancho Santa Ana Botanic Garden near Indian Hill. To the south, the expansion of the Ontario International Airport and the presence of the Chino Prison signal the increasing utility of the flatlands.
