About this map

Shell Beach and the neighboring settlements of Yscloskey and Alluvial City serve as the primary human outposts in this intricate landscape of marsh, lagoons, and bayous on the southern shore of Lake Borgne. The presence of Old Fort Beauregard near the coast hints at the strategic military importance of these waterways during earlier centuries. The map details a complex hydrologic network where Bayou Terre Aux Boeufs snakes through the wetlands toward Lake Amedee and Lake Jean Louis Robin, reflecting a delicate environment shaped by tidal influence and siltation.

Water navigation is central to life here, evidenced by landmarks like Alligator Point Light and various light daybeacons. To the east, the isolation of Saint Malo and the presence of Magnolia Mound suggest small habitable rises in a territory dominated by expansive water bodies such as Halfmoon Pass Bay and Grand Lagoon. This 1950s survey documents the coastal morphology and settlement patterns of St. Bernard Parish before significant late-20th-century environmental changes altered the shoreline.
