1994 Map of Calumet Island

About this map

East Timbalier Island stands as a fragile barrier between the Gulf of Mexico and the extensive industrial infrastructure of the late 20th-century Louisiana coast. This survey illustrates an environment defined by the extraction economy, where the Timbalier Bay Oil and Gas Field and Block 21 Oil Field dominate the seascape with a dense network of platforms and submerged pipelines. Protective measures like the Seawall along the barrier island and the presence of a Radio Tower and Bunk indicate a landscape heavily modified for energy production. Further inland, the map captures the isolated landforms of Calumet Island and Casse-Tete Island within Timbalier Bay, highlighting the transition from open water to the marshy periphery of Lafourche Parish. The inclusion of a Cut and various daybeacons reflects the vital navigation needs of this maritime industrial zone.
