The Sierra Madre mountains loom over the developing San Gabriel Valley floor in this mid-1920s survey. This era captures the region at a transitional moment, where citrus groves and rural tracts meet an expanding industrial and transportation network. The rail systems are particularly prominent, showing the Pacific Electric, Southern Pacific, and Atchison Topeka and Santa Fe lines intersecting near the San Gabriel River.
