1998 Map of Eastern Isles Dernieres

About this map

Isles Dernieres stretches across the center of this coastal survey, serving as a critical barrier between the Gulf of Mexico and the interior waters of Lake Pelto and Terrebonne Bay. The map documents a landscape defined by the intersection of conservation and heavy industry at the end of the twentieth century. Much of the land is designated as the Isles Dernieres Barrier Islands State Refuge, yet the surrounding waters are heavily developed for energy extraction. Numerous offshore structures are identified, including specific zones like the Isles Dernieres Oil Field, Trinity Bayou Oil Field, and the Block 8 Gas Field. Maritime navigation is traced through named channels such as Wine Island Pass, Pass la Poule, and Old Camp Pass, while interior landmarks like Bodwin and Edna provide fixed points amidst the shifting shoals and marshes of southern Louisiana.
