2024 Map of Calumet Island

About this map

East Timbalier Island stretches across the center of this coastal survey, serving as a narrow barrier between the open Gulf of Mexico and the protected waters of Timbalier Bay. This maritime landscape in southern Lafourche Parish is defined by its shifting island chains and expansive saltwater reaches, illustrating the modern state of Louisiana's fragile shoreline. Further north, the secluded landmasses of Casse-tete Island and Calumet Island sit within the bay, marked by the administrative grid of t23s r21e. The map captures a snapshot of these coastal features in a state of constant transition, where the interface of land and sea is primary and human settlement is notably absent, leaving only the natural topography and nautical boundaries to define the area.
