2024 Map of North Islands
USGS Topo · Published 2024About this map
The Chandeleur Islands form a fragile, arc-shaped barrier between the open Gulf of Mexico and the inner reaches of Saint Bernard Parish. This 2024 survey captures the fragmented state of these low-lying landforms, which are protected as part of the Breton National Wildlife Refuge and designated as the Breton Wilderness. The map reveals a landscape defined by water and shifting sands, where narrow strips of land are separated by tidal inlets and maritime passages like Smack Channel. This environment serves as a critical habitat for coastal wildlife, showing the intricate and ever-changing boundary of Louisiana's outermost edge.
