About this map

The Isles Dernieres barrier islands and the expansive coastal marsh of Terrebonne Parish are depicted here as they existed prior to decades of significant erosion and land loss. This mid-century survey, based on aerial photography by the Air Corps and U.S. Army, shows a complex network of waterways including Grand Pass Des Ilettes and Whisky Pass that separate the gulf-facing islands from the interior.
