About this map

San Bernardino stands as the primary hub of this late-nineteenth-century landscape, situated at the base of the San Bernardino National Forest and San Gabriel Mountains. The map reveals a complex web of early transportation, including the Southern California R. R. and the Highlands Motor Line, which facilitated growth in neighboring towns like Colton and Rialto. The irrigation-driven development of the San Bernardino Valley is evident through the presence of the Gage Canal and agricultural outposts such as Glen Helen Ranch and Grapeland.

To the south, the Santa Ana River snakes past the Jurupa Mountains and Rubidoux, marking the transition into Riverside County. Local industry and specialized settlements are scattered throughout, from the Quarry at Declezville to the celebrated Arrowhead Springs near Arrowhead Peak. This survey documents the region before the modern expansion of the Inland Empire, when the landscape was defined by mountain canyons like Cajon Canyon and the precision of the San Bernardino Base Line.
