Coastal waters and the low-lying wetlands of southeastern Louisiana define this landscape near the boundary of Plaquemines Parish. This 2018 survey illustrates a region dominated by the dynamic marine environment of the Gulf coast, where terrestrial features are sparse and the boundary between land and sea is constantly shifting. The absence of roads, settlements, or named inland landmarks reflects the extreme nature of this deltaic environment, which is primarily accessible by boat. For those studying the historical geography of the Mississippi River Delta, this map provides a precise baseline of the shoreline and administrative limits before further coastal erosion or sea-level changes alter the topography.
