About this map

Industrial and agricultural development define this Inland Empire landscape just before the mid-century boom. The rigid grid of the Fontana and Bloomington areas is bisected by a dense network of competing rail lines, including the Pacific Electric, Southern Pacific, and the Atchison Topeka and Santa Fe. To the south, the Jurupa Mountains rise abruptly, separating the growing valley settlements from the heavy industry near the Santa Ana River.

Evidence of local resource extraction is visible at the Quarry sites near Declezville and the significant Cement Plant at Crestmore, which is served by the Cement Plant Canal. Small community hubs like Sunnyslope and Glen Avon Sch appear amidst a landscape of irrigation infrastructure, such as the Fontana Aqueduct and Riverside Canal, which were essential for the region's citrus and grape industries before widespread suburbanization.
