2025 Map of Petit Bois Island

USGS Topo · Published 2025

About this map

Petit Bois Island stretches across this coastal survey, serving as a critical barrier between the Mississippi Sound and the open Gulf of America. As a primary component of the Gulf Islands National Seashore, the island's shifting sands and maritime environment are preserved as a natural buffer for the Mississippi and Alabama coastlines. This 2025 data shows the delicate state of the island's topography, highlighting the narrow landforms and marshy interior that define this offshore landscape. The map also delineates the maritime boundary between Mississippi and Alabama as it cuts through the sound just east of the island's edge, illustrating the administrative and geographic intersection of these two Gulf states.
