1973 Map of Bay Ronquille

About this map

Quatre Bayoux Pass serves as a critical break in the barrier islands, connecting the inner marshes of Plaquemines Parish to the Gulf of Mexico. This early 1970s orthophotomap provides a rare visual of the fragile marshland before significant coastal erosion altered the coastline. The landscape is defined by the industrial infrastructure of the era, with an Elevated Pipeline and numerous Platforms dotting the waters of Lake Grande Ecaille and Bay La Mer. These features, alongside the Ronquille Canal and various pipelines, reveal the extensive modification of the wetlands for resource extraction. Landforms like Point Cheniere Ronquille and the Grand Terre Islands provide a baseline for studying the shifting sediment and retreating shorelines of this tidal environment.
