2024 Map of Chandeleur Light

About this map

The Chandeleur Islands stretch through the eastern reaches of Saint Bernard Parish, serving as a critical barrier between the open Gulf of Mexico and the inner Louisiana coast. This maritime landscape is defined by the Breton National Wildlife Refuge and the dedicated Breton Wilderness, highlighting the conservation status of these remote landforms. The survey illustrates the shifting nature of these islands, where narrow strips of land face the direct forces of the Gulf. With no roads or permanent settlements present, the map focuses on the delicate relationship between the shorelines and the sea, documenting a geography shaped entirely by tidal action and coastal processes in the early twenty-first century.
