2020 Map of North Islands OE W

About this map

Chandeleur Sound dominates this coastal landscape in Saint Bernard Parish, representing a dynamic environment of shifting barrier island remnants. The map focuses on a largely maritime expanse where the North Islands appear as small, isolated features in the southeastern corner. This area, documented by the U.S. Geological Survey in 2020, illustrates the fragile nature of Louisiana's outer shoreline. Without the presence of permanent human settlements or infrastructure, the map serves as a primary record of natural landforms within the sound. It is an essential reference for understanding the geography of the Mississippi River Delta's eastern perimeter during the early twenty-first century.
