2012 Map of North Islands

About this map

The Chandeleur Islands form a narrow, shifting barrier arc within Saint Bernard Parish, separating the shallow waters of Chandeleur Sound from the open Gulf of Mexico. This coastal survey captures the precarious state of these landforms in the early twenty-first century, documenting a series of fragmented land masses that serve as a critical buffer for the Louisiana mainland. The landscape is defined entirely by hydrography and terrain, with no permanent structures, roads, or human settlements indicated on the islands. Instead, the map provides a precise record of the shoreline's configuration, offering essential data for those studying coastal erosion, migratory bird habitats, or the maritime history of this exposed section of the outer delta.
