2025 Map of Horn Island West

About this map

Horn Island stretches across the northern portion of this coastal survey, serving as a critical barrier between the Mississippi Sound and the open Gulf of America. As part of the Gulf Islands National Seashore, this segment of the island reveals a landscape defined by shifting sands and maritime topography. Notable coastal features such as The Horseshoe and the shallow waters of the Middle Ground illustrate the complex hydrography of the Mississippi coast. This contemporary record captures the island's footprint at a time of continued environmental change, providing a precise baseline for researchers tracking the evolution of the Gulf's barrier islands and protected maritime habitats.
