2020 Map of South Pass

About this map

Port Eads serves as the primary outpost on this coastal survey, situated at the extreme terminus of the Mississippi River delta. This maritime landscape is defined by the intricate branching of the South Pass, which channels river water into the Gulf of Mexico through a complex network of waterways including Grand Pass and Dennis Pass. The map documents a fragile environment of marshes and siltation, where family-named features like Valentiers Pond and Cognevich Pass suggest a long history of local navigation and commercial fishing. The presence of the Port Eads Sanitary Canal and sheltered anchorage in Whale Bay highlights the area's role as a vital staging point for deep-water marine operations and offshore industry. Inland, the terrain is dominated by shallow basins such as Morgan Pond and small rises like Lookout Island, providing a detailed view of the shifting deltaic geography in the early twenty-first century.
