2014 Map of Petit Bois Pass

About this map

Dauphin Island stretches along the northern edge of this coastal survey, terminating at the narrow spit known as West Point. This exposed geography defines the threshold between the relatively sheltered waters of the Mississippi Sound and the open Gulf of Mexico. The map details the shifting maritime boundary where the sound meets the sea through the Petit Bois Pass, a critical waterway for local navigation. The chart reflects the dynamic nature of Alabama's barrier islands, showing a landscape shaped by tidal currents and coastal processes. While largely dominated by water and sand, the area serves as a vital point of reference for the maritime history of Mobile County.
