2024 Map of Horn Island West

About this map

Horn Island stretches across the northern portion of this maritime survey, serving as a critical barrier between the Mississippi Sound and the open Gulf of Mexico. The island's geography is defined by its protected status within the Gulf Islands National Seashore and the Gulf Islands Wilderness, preserving a landscape of shifting sands and coastal inlets like The Horseshoe. Submerged features such as the Middle Ground characterize the shallow waters of the sound, illustrating the dynamic seafloor topography that governs navigation in Jackson County. This map documents the island's narrow profile and the distinct separation between the calm estuarine waters to the north and the high-energy coastal environment to the south.
