2024 Map of Petit Bois Island

About this map

Petit Bois Island stands as a slender barrier between the open Gulf of Mexico and the protected Mississippi Sound, a landscape shaped by shifting sands and maritime winds. This contemporary survey captures the island's dual status as both the Gulf Islands National Seashore and the more strictly preserved Gulf Islands Wilderness. The map highlights the invisible maritime and political boundaries that converge here, including the state line between Mississippi and Alabama and the county division between Jackson and Mobile counties. This isolation has preserved a unique coastal environment where natural processes continue without the interference of permanent infrastructure or roads.
