About this map

Sonoma Valley meets the marshlands of northern San Pablo Bay in this mid-century topographic record, where the intricate hydrology of the Sonoma Creek delta dominates the landscape. The area is defined by a network of engineered levees and sloughs, such as Steamboat Slough and Second Napa Slough, which weave through Tubbs Island and the neighboring Naval Reservation. These waterways supported a unique river-and-rail economy, evidenced by the Northwestern Pacific Railroad connecting small riverside outposts and agricultural camps.
