1918 Map of Collinsville

About this map

The confluence of the Sacramento River and the San Joaquin River defines this landscape at the heart of the California Delta. From the shoreline of Sherman Island to the uplift of the Montezuma Hills, the map illustrates a complex network of waterways including Montezuma Slough and New York Slough. Industry and transport converge at Antioch, where the Atchison Topeka And Santa Fe and Southern Pacific railroads parallel the waterfront. Numerous riverfront landings, such as Pittsburg Landing, Perley Landing, and Marsh Landing, highlight the maritime-dependent commerce of the early 20th century. This survey reveals a transition from the agricultural expanses of the delta islands to the developing rail hubs on the southern shore, documenting the area as it appeared prior to mid-century industrial expansion.
