2018 Map of Horn Island East

About this map

The barrier islands of the Gulf Islands National Seashore stand at the edge of the Mississippi Sound, providing a record of the shifting coastal geography of Jackson County. This coastal survey highlights the slender profile of Horn Island and the western tip of Petit Bois Island, separated by the deep waters of Horn Island Pass. These islands are dynamic features, constantly reshaped by the currents of the Gulf of Mexico. Navigation is a central theme here, with the Pascagoula Channel cutting through the Mississippi Sound to provide deep-water access for the region's maritime industry. For local historians and researchers, the map documents the relationship between these protected landforms and the essential shipping lanes that have long sustained the coastal economy of Mississippi.
