About this map

Grande Ecaille Oil Field marks the northern reaches of this coastal landscape, where industrial extraction meets the complex marshlands of the Mississippi River Delta. Compiled from 1935 aerial photographs by the Air Corps and U.S. Army, this map captures the intricate network of tidal bays and bayous before mid-century coastal erosion significantly altered the shoreline. The boundary between Plaquemines Parish and Jefferson Parish cuts through the western waters, specifically through Bay Ronquille and down toward Quatre Bayou Pass. This transitional zone is characterized by low-lying features like Pt Cheniere Ronquille and the eastern tip of Grande Terre, documenting a fragile environment of narrow ridges and sprawling water bodies including Lake Grande Ecaille and Bay Long at the edge of the Gulf of Mexico.
