The Southwest Pass shipping channel cuts a deep, engineered path through the Mississippi River Delta as it empties into the Gulf of Mexico. This coastal landscape in Plaquemines Parish is defined by fragmented wetlands and shifting sediment, where Burrwood Bayou and Stake Island Bayou thread through the low-lying marsh. The geography here is a complex interface of fresh and saltwater, evidenced by the large expanses of West Bay and Mud Bay that flank the primary navigation corridor. For those studying maritime history or the evolving hydrology of the Louisiana coast, this survey reveals the modern configuration of these critical waterways and the thinning landforms that protect the interior pass from the open gulf.
