Mulberry Island sits at the edge of the Gulf of Mexico, defining a landscape where the coastal marshes of Vermilion Parish meet the open sea. This 2015 survey reveals a terrain dominated by strategic ridges and artificial waterways, reflecting the region's managed coastal hydrology. Elevated ground follows a series of distinct landforms including Beef Ridge, Bill Ridge, Sand Ridge, and Front Ridge, which provide subtle relief amidst the surrounding wetlands. These ridges likely represent historical cheniers—relict beach ridges that serve as vital high ground in the deltaic plain. The primary north-south artery for both navigation and drainage is the Freshwater Bayou Canal, complemented by Freshwater Bayou and the east-west Dewitt Canal. Road access is limited to the winding path of La-3147, which navigates the interior between these watery boundaries.
