About this map

Gulf of America dominates this hydrographic study of the southern tip of Plaquemines Parish, where the Mississippi River delta meets the open sea. The map documents the shifting maritime landscape of coastal Louisiana, defined by narrow channels and tidal basins. Key waterways like Pass Du Bois and Pass La Graisse provide critical navigation data for this ecologically sensitive maritime region. These features illustrate the dynamic nature of the deltaic wetlands, where water levels and shoreline integrity are constantly influenced by the surrounding West Bay. As a modern topographic record, it captures the current state of these vital passes and coastal inlets before further natural or industrial changes alter the topography of the Gulf coast.
