About this map

Horn Island stretches across the center of this 1941 survey, serving as a critical barrier between the Gulf of Mexico and the Mississippi Sound. The map illustrates the island's shifting topography, characterized by extensive Sand Dunes and small marshy inlets along its interior. The northern shore is defined by the Intracoastal Waterway, a vital maritime artery for the Gulf Coast economy during the early 1940s.

To the east, the Pascagoula Channel and Horn Island Pass mark the deep-water transition toward Petit Bois Island. This document captures the uninhabited state of these barrier islands as they appeared just before mid-century, recording the natural coastal formations and navigation channels that governed Jackson County's offshore maritime traffic. The survey by J.A. McKeon provides a precise look at the island's isolation and its role in protecting the mainland sound.
