2015 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 Mexico. Part of the Gulf Islands National Seashore, this specific section of the barrier island chain includes the distinctive landform known as The Horseshoe. The map illustrates the delicate boundary of Jackson County as it transitions from the shallow sound waters to the deep maritime environment of the Gulf. This 2015 data reflects the modern shoreline of the island, which is subject to constant movement and reshaping by tides and storm surges. The lack of inland development highlights the protected status of the island, preserving the native terrain as it appeared before the modern expansion of the Mississippi coastline.
