About this map

The Jurupa Mountains dominate the southern portion of this landscape, separating the developing citrus and vineyard belts from the industrial and riverine corridors of the Santa Ana River. At this time, Fontana and Rialto are organized around a strict grid of avenues and boulevards like Foothill Boulevard and Arrow Highway, served by a dense network of competing rail lines including the Pacific Electric, Southern Pacific, and the Atchison Topeka and Santa Fe.

Extractive industry is prominent, marked by numerous Quarry sites and a large cement plant near Crestmore. The presence of small settlements like Declezville, Sunnyslope, and Ennis suggests a period of transition as rural agricultural holdings met industrial expansion. Local community life is anchored by landmarks such as the Glen Avon Ch and Glen Avon Sch south of the mountains, while the extensive canal system including the Jurupa Canal underscores the region's reliance on managed water for its growth.
