2025 Map of North Islands

About this map

Chandeleur Islands stretch through the waters of the Gulf of America in this remote maritime survey of Saint Bernard Parish. The map reveals a fragmented landscape of sand and marsh as it appeared in the early 2020s, showing a thin crescent of land disconnected from the mainland. This environment is defined by its shifting shoals and the prominent passage of Smack Channel to the south. Because these islands are highly susceptible to coastal erosion and storm surges, the document provides a critical look at the shoreline's configuration at this specific point in time. It serves as a grounded record for those studying the physical evolution of the Louisiana coast, capturing the exact footprint of these barrier features before further environmental changes occur.
