1935 Map of Grand Island Pass

About this map

Grand Island sits at the maritime intersection where Lake Borgne meets the Mississippi Sound, marking a critical geographical point on the state line between Mississippi and Louisiana. This 1935 field examination, compiled from aerial photography by the Air Corps and U. S. Army, delineates a landscape of marshy inlets and coastal waterways. The map illustrates the precarious nature of this marshland territory, where features like Grassy Id and Pt Clear define the transition from open water to estuarine environments.
