About this map

Port Sulphur sits at the heart of this coastal Plaquemines Parish landscape, where the Mississippi River dictates the pattern of human settlement. In the mid-1930s, development is concentrated along the river's western bank, following the corridor defined by the Missouri Pacific railroad and State Highway No 31. This narrow strip of higher ground supports the communities of Potash PO and Homeplace PO, as well as the Milan Ch.

Beyond the river levees, the map reveals an intricate network of wetlands and tidal waters. A labyrinth of canals, such as the Sulphur Co Canal and Socola Canal, cuts through the marsh to reach interior water bodies like Lake Washington, Bay Lanaux, and Bay de la Cheniere. This 1935 survey captures the transition from industrial riverfront activity to the expansive, undisturbed bays and bayous of the delta before later twentieth-century coastal changes.
