The Mississippi River carves through the lower delta in this detailed 2015 study, with the settlement of Port Sulphur anchoring the western bank. This area of Plaquemines Parish shows the intricate relationship between the river's main channel and the surrounding marshlands, evidenced by the Pointe A La Hache Relief Outlet and the complex web of canals like Fosters Canal. The landscape is dominated by a fragile network of coastal features such as Grand Point Bay and Drum Island, separated by numerous passes including Triple Pass leading toward the Gulf of Mexico. Smaller communities like Happy Jack, Point Michel, and Encalade are clustered along the river corridor, following the higher ground established by natural levees and reinforced by infrastructure like La 23. The presence of the Bohemia Cem on the eastern bank serves as a silent reminder of earlier settlement patterns in this dynamic estuarine environment.
