1903 Map of Cucamonga

About this map

The San Gabriel Mountains dominate the northern landscape of this region, dropping sharply into the alluvial plains where citrus groves and early settlements flourished. Surveyed in the late 19th century, the map captures the structured growth along the San Bernardino Base Line. Transportation is the defining characteristic of the valley floor, with a dense network including the Atchison Topeka and Santa Fe R. R. and the Southern Pacific R. R. facilitating the movement of agricultural goods from centers like Upland and Ontario.
