About this map

Mississippi Sound borders a complex system of marshes and tidal inlets in this coastal survey of St. Bernard Parish. The landscape is defined by its transition from open water into a labyrinth of named bayous and bays, such as Turkey Bayou and Johnson Bay. This environment reflects the dynamic coastal geography of Louisiana in the mid-1950s, where small landmasses like Raccoon Island and Shell Island provide minimal solid footing among the expansive wetlands.

Strategic points of land, including Negro Point and Shell Point, serve as natural markers for navigation through Three Mile Pass. The intricate network of interior waterways like Drum Bayou and Creque Bayou illustrates the natural drainage patterns before significant modern alteration. For those researching the maritime and environmental history of the Gulf Coast, this documentation provides an essential record of these fragile coastal landforms and named reaches.
