1953 Map of Central Isles Dernieres

About this map

Isles Dernieres stretches across this coastal survey, forming a thin barrier between the marshy interior and the open Gulf of Mexico. The landscape is dominated by a complex network of tidal passes and bayous, including Grand Pass des Ilettes and Whiskey Pass, which define the fragmented shoreline of Whiskey Island. This mid-century study, based on 1952 aerial photography and 1953 planetable surveys, captures the delicate state of the Louisiana coast before significant modern erosion altered these landforms.
