1956 Map of Isle Au Pitre

About this map

The marshy southern reaches of the Mississippi Sound and the northern fringe of Chandeleur Sound dominate this coastal survey. The most prominent landmass is the island of Isle Au Pitre, a complex of wetlands and inlets featuring Creole Gap and Bayou Pierre. To the north, the tip of Cat Island is identified by the Juan De Cuevas Claim Cat Island, marking a significant land title at West Point. Maritime navigation is the primary focus of this data, evidenced by the Intracostal Waterway Project Depth 12 Feet and various channels such as Shell Bank Channel. This map captures a fragile coastal environment before significant late-20th-century erosion, documenting shoals like Pelican Key and the sprawling Isle au Pitre Bank that define the border between Mississippi and Louisiana.
