1971 Map of Dixon Bay

About this map

Southwest Pass serves as the dominant navigational artery in this 1971 orthophotomap of the Mississippi River Delta. The landscape is a complex mosaic of marsh and open water, where natural features like Bob Taylors Pond and Joseph Bayou reveal the intricate hydrology of Plaquemines Parish. Industrial activity is pervasive throughout the area, evidenced by numerous oil wells, platforms, and sludge pits scattered across Zinzin Bay and Scott Bay. To the east, the Pass A Loutre State Waterfowl Management Area covers a significant portion of the delta, protecting the tidal wetlands. This survey provides a precise visual of the shoreline before decades of coastal erosion further altered the deltaic landforms, capturing the specific locations of remote infrastructure like a Helicopter Pad and Radio Tower that supported the offshore energy industry.
