1955 Map of Isle Au Pitre

About this map

Isle Au Pitre and the surrounding waters of the Mississippi Sound define this coastal boundary area where Louisiana meets Mississippi. The map documents the shifting sands and shoals of the Mississippi Sound at the mid-century, including the Juan De Cuevas Claim Cat Island and its prominent West Point lighthouse. The complex hydrography of the region is illustrated through a network of maritime passages such as the Intracoastal Waterway, South Pass, and Shell Bank Channel. Marine landmarks like Cabbage Reef, Pelican Key, and the Tail of the Square Handerchief Shoal provide crucial navigation points for the coastal economy. Along the southern edge of the sheet, the wetland environment of St. Bernard Parish is visible through features like Bayou Pierre and Creole Gap, showing the fragile transition between marshland and the open sound.
