2020 Map of South of South Pass

About this map

South Pass marks the edge of the Mississippi River delta, where the land fragments into the open expanse of the Gulf of Mexico. This 2020 survey of Plaquemines Parish reveals the transitional environment at the very foot of Louisiana, an area dominated by maritime hydrography and wetland inventory data. In this corner of the Mississippi River Delta, the boundary between terrestrial features and the sea is fluid, showing the dynamic nature of the bird’s-foot delta as it extends into deep water. The map provides a precise geodetic record of the shoreline and offshore waters, essential for understanding the shifting coastal morphology of the Gulf Coast.
