1958 Map of Isle Aux Herbes

About this map

The salt marshes and shallow waters of Mississippi Sound dominate this 1950s hydrographic and topographic study of Mobile County's coastline. The map focuses on the barrier islands and estuarine environment of the Gulf, most notably the large expanse of Isle Aux Herbes and the smaller Isle aux Dames. The coastal landscape is defined by the transition from open water to protected inlets like Grand Bay and Porters Ville Bay, separated by Pt aux Pins. Human intervention in this maritime environment is evident through the path of the Intracoastal Waterway and a designated Spoil Area near the shoals. Mariners and researchers can find specific soundings and navigation aids, including a light marking the passage between the islands and the mainland.
