2025 Map of Breton Islands

About this map

Breton Islands stand as isolated remnants of the Mississippi River delta’s historical shifts within Plaquemines Parish. This map documents a fragile coastal landscape defined by the expansive Breton Sound to the north and the open Gulf of America to the south. The islands' low-lying profile is marked by points of reference like North Point and West Point, which serve as crucial navigational landmarks in an area dominated by marine environments. As part of a larger archipelago, these features are central to the region's ecological identity, providing a look at the modern state of Louisiana's barrier island systems and the shifting bathymetry of Breton.
