1946 Map of Isle Au Pitre

USGS Topo · Published 1946

About this map

The coastal waters of Mississippi Sound and the intricate marshlands of Isle au Pitre define this mid-century maritime survey. Positioned along the border between Mississippi and Louisiana, the map illustrates a complex network of waterways including South Pass, Grand Pass, and the wide Cat Island Channel. Navigation was critical in these shallows, marked here by the Merrill Shell Bank LH and Cat Island LH. The landscape is dominated by the shifting morphology of islands and wetlands, with Cat Island showing its prominent West Pt and interior marsh pockets. This coastal chart captures the precise boundary where Harrison County and St. Bernard Parish meet, revealing the natural hydrology of Bayou Pierre and Little Bayou Pierre before the significant shoreline changes of the later twentieth century.
