Industrial infrastructure and maritime navigation define this coastal survey of St. Bernard Parish, dominated by expansive energy extraction zones like the Block 25 Oil and Gas Field and the Treasure Bay Gas Field. Multiple offshore platforms are precisely located across the shallow waters of Morgan Harbor and Eloi Bay, marking the active economic footprint of the Gulf at this time. The landscape is a labyrinth of salt marsh and tidal waterways, featuring intricate passages like Jules Cutoff, Treasure Bay Pass, and the prominent Bayou La Loutre. Geographic landmarks such as Dry Bread Island, Point Eliza, and Point Cahill provide essential orientation for navigation within Chandeleur Sound. This map serves as a vital record of the Louisiana coastline's specific shoreline configurations and industrial development before the significant erosional changes of the late 20th century.
