1982 Map of Horn Island East

About this map

Horn Island stretches across the northern portion of this maritime survey, illustrating the fragile geography of Mississippi’s barrier islands in the early 1980s. As part of the Gulf Islands National Seashore, the island is separated from the mainland by the Mississippi Sound and faces the open Gulf of Mexico to the south. The map details the shifting sands and underwater topography of the Horn Island Pass, a critical maritime gateway where several Lights and a deep-water Channel facilitate navigation. The eastern tip of the island and the western edge of Petit Bois Island show the dynamic nature of these coastal landforms, where tidal currents and storms continuously reshape the shoreline. This cartographic study, compiled from aerial photography and hydrographic charts, records the precise boundaries of this protected wilderness area before decades of subsequent hurricane activity further altered the archipelago.
