About this map

Gulf Islands National Seashore encompasses a fragile chain of barrier islands off the Mississippi coast, providing a critical buffer between the Mississippi Sound and the open Gulf of Mexico. This maritime landscape is defined by the elongated stretch of Horn Island and the smaller fragments of West Petit Bois Island and Petit Bois Island to the east. These shifting sands are separated by navigable waters including the Horn Island Pass and the Pascagoula Channel, which serve as vital conduits for maritime traffic entering from the gulf.

The coastal geography shown here reflects the dynamic nature of the Mississippi Sound's outer reaches. These islands are not static landmasses but active environments shaped by tide and current. For researchers of coastal change or maritime history, the map provides precise positioning of these landforms as they existed in recent years, documenting the specific contours of the pass and the isolation of these protected offshore environments.
