1942 Map of Horn Island

About this map

Horn Island stretches narrowly across the center of this 1941 survey, separating the sheltered waters of the Mississippi Sound from the open Gulf of Mexico. Surveyed by J.A. McKeon for the War Department, the map captures the shifting barrier island geography just before the height of World War II. The landscape is defined by vast expanses of Sand Dunes and shifting Sand deposits, illustrating the dynamic nature of these coastal landforms. To the east, the map details the beginning of Petit Bois Island and the navigable Horn Island Pass, providing a technical look at the maritime channels and maritime topography of Jackson County during this era.
