About this map

The Isles Dernieres barrier chain marks the fragile boundary between the Gulf of Mexico and the marshy interior of Terrebonne Parish. This coastal landscape is defined by its industrial footprint, featuring extensive offshore infrastructure such as the Bay Round Gas Field and the Pelican Lake Gas Field. Numerous platforms dot the waters of Caillou Bay and Pelican Lake, illustrating the intense energy extraction of the late twentieth century.

Dynamic aquatic corridors like Whiskey Pass and Coupe Nouvelle separate the narrow landforms of Whiskey Island and Trinity Island. These sandy reaches, constantly reshaped by the sea, provide a baseline for studying coastal erosion and the shifting geography of Louisiana's fringe. The map also identifies specific local points of interest such as Villette2 and Bogue, serving as precise markers in an otherwise fluid environment of bayous and bays.
