About this map

Old Harbor Island sits at the southern edge of this maritime quadrangle in Saint Bernard Parish, Louisiana. This 2015 survey documents a vast aquatic landscape where the open waters of the Gulf of Mexico meet the protected reaches of Chandeleur Sound. This specific region is characterized by its dynamic coastal geography, where small landforms like Old Harbor Island serve as critical markers for navigation and historical shoreline studies. The absence of traditional roads or settlements underscores the isolation of these outer islands, which are essential for understanding the shifting environmental history of the Mississippi River Delta's eastern fringe.
