2018 Map of North Islands

About this map

North Islands form a narrow, fragmented chain of barrier landforms in this 2018 survey of Saint Bernard Parish. These features separate the relatively sheltered waters of Chandeleur Sound from the open Gulf of Mexico. The map illustrates a landscape defined by coastal processes, where small, stippled land masses are all that remain of this northern section of the archipelago. There are no roads, buildings, or human-made structures indicated on these islands, emphasizing the maritime nature of this territory. The mapping provides a technical record of the shoreline geometry and wetland distribution during the late 2010s, capturing the shifting relationship between the sound and the sea.
