The San Gabriel Mountains dominate the northern landscape of this late nineteenth-century survey, with the San Gabriel River carving a deep path through the canyonlands. At the base of these heights, a string of citrus-era settlements including Azusa, Glendora, and Monrovia follow the natural break between the mountains and the valley floor. The map documents the early grid of Pomona and the competing rail lines that fueled the region's development. The Atchison Topeka and Santa Fe RR and the Southern Pacific RR cross the basin, connecting once-distinct communities like Lordsburg and Spadra. Distinctive land grants like San Jose Addition and La Puente are clearly delineated, showing the legal foundations of the land before it was fully subdivided. This record captures the transition from ranching heritage to an established railroad-and-orchard economy.
