The Southwest Pass shipping channel dominates the fragile, shifting geography of the Mississippi River delta in this coastal study. Situated in the southernmost reaches of Plaquemines Parish, the landscape is defined by the thin strips of land separating the river's outflow from the surrounding waters of the Gulf of America. This area is a critical maritime corridor where the river meets the sea, featuring the narrow passage of Burrwood Bayou and the tidal flats of Mud Bay. The map provides a contemporary record of the land-water interface at Stake Island Bayou and West Bay, documenting the current state of a region where sediment deposition and coastal erosion constantly reshape the terrain. For those interested in the hydrology of the birdfoot delta, the intricate network of distributary channels shown here reveals the complex plumbing of one of North America's most important industrial and ecological waterways.
