About this map

Marsh Island dominates this coastal landscape, where the southern reaches of the Russell Sage Foundation-Marsh Island State Wildlife Refuge meet the open waters. The terrain is defined by shifting hydrology, with the West Branch and East Branch feeding into Oyster Bayou as it empties near Mound Point. To the east, the island terminates at South Point before giving way to the expanse of East Cote Blanche Bay.

Further offshore in the Gulf of Mexico, the Shell Keys National Wildlife Refuge marks a critical environmental boundary. The map provides extensive hydrographic data, including soundings and the positioning of numerous Shell Reefs that navigate the shallow coastal shelf. This 1968 revision captures a specific moment in the geomorphology of the Louisiana coast, illustrating the intricate relationship between marshland drainage and the advancing gulf.
