Isle Au Pitre and the surrounding marshlands of St Bernard Parish anchor this coastal survey, where the borders of Louisiana and Mississippi meet in the shallow waters of the Mississippi Sound. This map represents an advance sheet compiled from 1930s aerial photography, documenting the complex estuarine environment before significant modern coastal erosion and engineering. Maritime navigation is central to the area's geography, evidenced by the Merrill Shell Bank LH and Cat Island LH guarding the approaches to Marianne Pass and South Pass. To the south, the intricate network of Bayou Pierre and Little Bayou Pierre reveals a landscape dominated by tidal flow and marshy inlets like Creole Gap, essential for understanding the historical shoreline of Drum Bay and the vicinity of Door Point.
