1958 Map of Isle Aux Herbes

About this map

The coastal waters of Mobile County are captured here just before the end of the 1950s, centered on the marshy expanse of Isle Aux Herbes. This hydrographic survey documents the navigational landscape of the Mississippi Sound and Portersville Bay, focusing on the shallow reaches and barrier islands that define the Alabama coastline. The charting reflects a mid-century maritime economy dependent on the Intracoastal Waterway, which is noted with a Project Depth 12 Feet at the bottom of the sheet.
