About this map

Russell Sage Foundation - Marsh Island State Wildlife Refuge dominates this coastal landscape, protecting a complex labyrinth of bayous and brackish lakes along the Louisiana shoreline. The 1968 environment is defined by its industrial and recreational intersections, featuring offshore energy production in the Vermilion Bay Oil and Gas Field and West Cote Blanche Field alongside public spaces like Cypremort Point Beach.

A network of named water bodies including Lake Jefferson, Lake Michael, and Lucien Lake characterizes the interior marsh, while significant coastal landmarks such as Grosse Isle Point and Mound Point anchor the southern edge against the Gulf of Mexico. Navigational markers like the Radio Tower and the Quintana Canal illustrate the infrastructure required to manage this fluid geography during the late 1960s.
