About this map

Lake Athanasio and the surrounding marshlands of St. Bernard Parish define this coastal landscape during the mid-2010s. The map illustrates a complex network of estuarine waters where the Mississippi River-Gulf Outlet Canal cuts through the wetlands, connecting larger bodies like Lake Eloi and Seven Dollar Bay. The area is characterized by shifting shorelines and low-lying landforms such as Gardner Island and Grassy Island, positioned between the inland bayous and the open Gulf of Mexico.

Coastal geography dominates the southern portion of the sheet, where Pass Fernandez and Point Gardner mark the transition into Black Bay. The interface between Plaquemines Parish and its northern neighbor is traced through these waterways, providing a detailed record of the navigable channels like Canal Pecal and Mulatto Bayou before further coastal erosion or industrial changes altered these traditional fishing and trapping grounds.
