Mulberry Island sits at the southern edge of this coastal landscape in Vermilion Parish, where the marshy terrain meets the vast waters of the Gulf of Mexico. The area is defined by the Public Land Survey System grids of T16S R1W, T16S R1E, and T17S R1E, illustrating how the low-lying wetlands were historically partitioned. A primary human-made feature is the Dewitt Canal, which cuts through the northern sections and tracks south toward the shoreline. This 2018 survey captures a remote segment of the Louisiana coast focused almost entirely on the transition from inland marsh to the open gulf, with few permanent structures or named roads, emphasizing the region's focus on water management and coastal geography.
