About this map

Sonoma Valley meets the tidal marshlands of San Pablo Bay in this mid-century survey, revealing a landscape defined by complex water management and rail transportation. The Northwestern Pacific Railroad and Southern Pacific lines converge near Schellville, anchoring a network of tracks that served the region's agricultural and industrial needs. Levees and pumping stations crisscross the marshes around Tubbs Island and Island No 1, managing the flow of Sonoma Creek and Napa Slough.

To the west, the Petaluma Mountains rise sharply from the valley floor, featuring landmarks like Wildcat Mtn and the upland waters of Gravelly Lake. Small settlements and social hubs such as Wingo, Fairville, and the Sonoma Valley Club dot the transition zone between the hills and the bay. The map also captures the boundaries of the Naval Reservation, reflecting the military's strategic footprint along the North Bay shoreline during the early 1950s.
