About this map

Southwest Pass serves as the primary maritime gateway in this coastal landscape where the waters of the Gulf of Mexico meet the intricate marshes of Iberia and Vermilion Parishes. The coastal geography is defined by low-lying features such as Deadman Island and Tojan Island, which are situated amidst a network of tidal channels including Hell Hole Bayou and Hog Bayou. These waterways illustrate the fragile transition between the open gulf and the sheltered reaches of Vermilion Bay.

Maritime history and navigation are evidenced by landmarks such as Lighthouse Point and Porpoise Point on the western edge of Marsh Island. Submerged features like Tete Butte Reef reflect the hazards and habitats of this littoral zone. The map documents a sparsely populated but ecologically complex coastal environment, capturing the shifting boundaries where Portage Lake and Bird Island Bayou intersect with the larger gulf system.
