Mitchell Island and the surrounding marshlands of Saint Bernard Parish reveal a complex coastal landscape defined by shifting passes and shallow bays. This maritime environment is punctuated by small landmasses like Martin Island and Turtle Pen Isle, which serve as vital markers in the labyrinth of the Louisiana coast. The waterways here, including Elephant Point Pass and Keelboat Pass, dictate the movement of water and craft through the sound, illustrating the fragile geography of the outer delta.
