1933 Map of Ontario

USGS Topo · Published 1933

About this map

The citrus groves and growing industrial centers of the Inland Empire are captured in detail during the early 1930s. The dense street grid of Ontario and Upland reveals a landscape organized by rail and road, where Foothill Blvd U S Highway No 66 and the Arrow Highway serve as primary east-west arteries. The area's transit heritage is visible through the converging lines of the Pacific Electric, the Atchison Topeka and Santa Fe, and the Southern Pacific railroads, which facilitated the movement of goods from local packing houses and farms.
