2020 Map of Isle aux Herbes

About this map

Mississippi Sound and the intricate coastal geography of Mobile County are captured here, centered on the marshy reaches of Isle aux Herbes and Terrapin Island. This maritime landscape is defined by its barrier features and shallow estuaries, where Grand Bay meets the mainland at Point aux Pins. The map documents the critical maritime corridor of the Intracoastal Waterway as it passes north of Dauphin Island, providing a technical look at the various landforms and small islets like Isle aux Dames and the Grande Batture Islands that shift with the tides and storms of the Gulf. Though largely devoid of permanent structures, the survey provides precise positioning for the Sandy Bay shoreline and the township boundaries of t8s r3w.
