2018 Map of Calumet Island

About this map

Timbalier Bay and the open Gulf of Mexico dominate this coastal survey of Lafourche Parish. The landscape is defined by fragmented landforms and barrier islands, including the small northern outcrops of Casse-tete Island and Calumet Island. Further south, the elongated East Timbalier Island stands as a fragile boundary against the gulf. This 2018 documentation illustrates the minimal terrestrial footprint in this portion of the Louisiana delta, where township boundaries like t23s r21e and t24s r21e largely cross open water. For researchers, the map provides a precise record of the shoreline and island positions as they existed during the mid-2010s, reflecting the dynamic nature of this wetland environment.
