About this map

The San Gabriel Timberland Reserve dominates the northern half of this landscape, a complex system of deep canyons like Graveyard Canyon and Horse Canyon that drain into the San Gabriel River. Below the foothills, the late 19th-century citrus belt is in its formative years, shaped by an intricate network of irrigation including the Azusa Ditch and Covina Canal.

Settlement patterns follow the competing tracks of the Atchison Topeka and Santa Fe RR and the Southern Pacific RR, which connect established hubs like Pomona and Azusa with smaller railroad stops such as Lordsburg, Spadra, and Vineland. The presence of the San Jose Addition and San Jose land grants reflects the region's transition from massive ranchos to subdivided agricultural and residential tracts. Rare local features like the Club House near the West Fork suggest the early recreational value of the mountains even as the valley floor industrialized.
