About this map

West Black Bay Oil and Gas Field dominates the marine environment of this 1970s coastal survey, illustrating the industrial footprint of offshore extraction in Plaquemines Parish. The orthophotomap imagery reveals a complex landscape of shifting marshland and open water where Black Bay meets Breton Sound. Isolated landforms such as Belle Isle, Stone Island, and Lonesome Island punctuate the aquatic expanse, serving as essential landmarks for navigation alongside numerous oil platforms and a Radio Tower. The southern portion of the map includes part of the Bohemia State Wildlife Management Area, highlighting the intersection of resource extraction and conservation. Intricate waterways like Bel La Pass and Bayou Lost demonstrate the fluid nature of the Louisiana shoreline before significant subsidence further altered these coastal reaches.
