2025 Map of Chandeleur Light OE W

About this map

Hewes Point stands as a primary geographic marker in this maritime region of Saint Bernard Parish, positioned where the barrier landscape meets the open waters. This survey documents the reach of the Chandeleur Sound as it transitions into the Gulf of America, providing a specialized view of the coastal shelf and navigation environment in the 2020s. Unlike more terrestrial maps, this sheet focus almost entirely on the hydrographic boundary, making it an essential reference for understanding the modern shape of these vulnerable outer barrier islands and their relationship to the surrounding seafloor.
