The Gulf of Mexico dominates this coastal survey south of St. Mary Parish, illustrating the shifting maritime landscape of southern Louisiana. The map focuses on the submerged and semi-submerged environments where the Louisiana marshlands meet the open sea. Named waterways like New Pass and Ann Channel serve as the primary markers in an otherwise open expanse of water, highlighting the critical passages used by local mariners and industry. This chart serves as a precise record of the shoreline and coastal depth at a specific moment in time, providing essential context for understanding the geomorphology of the Belle Isle region without the clutter of inland development.
