About this map

Ft Livingston Ruins stand as a silent sentinel at the entrance to Barataria Pass, marking the precarious intersection of historical coastal defense and the shifting barrier islands of the Gulf. This early 1970s orthophotomap details the eastern tip of Grand Isle, where the Coast Guard Station and the recently established Grand Isle State Park (East End) represent the modern human footprint against an environment dominated by marsh and tide. The landscape is defined by its complex hydrology, with Bayou Rigaud and Bayou Fifi providing essential channels for the local maritime economy.

Industrial activity is evident further north at the Queen Bess Island Oil and Gas Field, illustrating the post-war expansion of energy infrastructure into the wetlands. Navigation remains a central theme, traced through the Barataria Bay Waterway and various lights and platforms that guide traffic through the Grand Terre Islands. The map provides a precise view of the fragile geomorphology of Pelican Island and Beauregard Island before subsequent decades of coastal erosion.
