1931 Map of Bay Side

About this map

Cohansey Creek snakes through the tidal marshes of Cumberland and Greenwich in this 1931 edition, which details the maritime and agricultural life of the lower Delaware River. Inland, the map reveals a landscape defined by small mill operations and rural centers like Shiloh and Roadstown. Significant industrial and navigational markers include Sheppard Mills and Laning Wharf, illustrating how local commerce relied on both the Southern Jersey R R and the surrounding waterways. Across the river on Bombay Hook Island, the survey captures the complex drainage systems of Bear Swamp and Leatherberry Flats. Navigational safety for the bay's traffic is anchored by the Cohansey Light Old Light and the offshore Ship John Light, marking the transition from river to bay. This survey combines 19th-century topography with 1920s revisions and early aerial photography from the U.S. Army Air Corps.
