About this map

Lake Borgne and the surrounding coastal marshlands dominate this mid-1990s environmental record of the Louisiana shoreline. The landscape is defined by the extraction of natural resources, with expansive underwater infrastructure including the Lake Borgne Gas Field, Shell Point Gas Field, and the Unknown Pass Oil and Gas Field marking the territory. The Intracoastal Waterway cuts a straight path through the wetlands, connecting Lake St Catherine to the larger bay system, while natural outlets like Unknown Pass and Miller Bayou maintain the ancient tidal flow of the delta.

Local landmarks such as Alligator Point, Point Cataline, and Shell Point serve as the primary terrestrial markers in an area where the boundary between land and water is often indistinct. The survey also captures the parish line separating Orleans Parish and St Bernard Parish, illustrating how political boundaries traverse these remote coastal reaches. This map provides a clear view of the industrial and hydrological state of the region shortly before the significant coastal changes of the late 20th century.
