Lake Borgne and the Mississippi Sound meet in this 1935 coastal survey, depicting the complex brackish marshlands along the Louisiana and Mississippi border. Compiled from aerial photographs taken by the Air Corps, the map captures the intricate hydrology of the Grand Island Pass area before modern coastal erosion significantly altered these shorelines. The landscape is dominated by tidal features and small landmasses like Grassy Id and Lower Pt Clear, which served as critical navigation markers for mariners traversing the inner passage between the two states.
