About this map

Riverside serves as the focal point for this late-Victorian era survey, illustrating the complex irrigation and transportation infrastructure that supported the region's citrus and mining industries. The map traces the vital courses of the Riverside Canal and Gage Canal, which transformed the arid landscape near Arlington and Casa Blanca. Further south, the terrain shifts into the uplands of El Sobrante De San Jacinto, where resource extraction is evident at the Cajalco Tin Mine and Gavilan Mine.

Transit networks are extensively documented, including the Southern California R. R. and the prominent boulevard of Magnolia Avenue. Small rail-stop settlements like Alessandro and Valverde appear on the plains east of the Box Springs Mountains, while the Santa Ana River marks the northern limit of the Jurupa territory. This map documents a period when the agricultural grid was still expanding into the foothills of The Gavilan.
