About this map

Corona sits at the heart of this landscape, its grid organized by iconic thoroughfares like Ontario Avenue and Magnolia Avenue during an era of significant citrus production and local development. The drainage of the Santa Ana River and the Temescal Wash dominates the terrain, with the Sierra De San Jacinto and the Santa Ana Mountains framing the basin. North of town, the specialized character of Norco is visible near Lake Norconian, a site of notable social and architectural prominence at the time of the survey.

Industrial and institutional activity is scattered across the valley, from the Quarry operations near the wash to the Sherman Institute Farm. Educational and social hubs like La Sierra College in La Sierra Heights and the Eastvale Sch highlight the growing community structure. Transportation is anchored by the Atchison Topeka and Santa Fe Railroad and the Pacific Electric Highway, connecting this inland agricultural hub to the broader Southern California network.
