About this map

Bastian Island and Lanaux Island stand as isolated landmarks within the fragmented coastal landscape of Plaquemines Parish. This maritime survey documents the intricate network of waterways where the Gulf of Mexico meets the Louisiana wetlands. Significant tidal openings like Chaland Pass, Grand Bayou Pass, and Bastian Pass facilitate the exchange between the open gulf and protected interior waters.

Inland, the geography is defined by a series of named bayous and bays, including Bayou Chaland, Bayou Huertes, and Garden Bay. The lack of terrestrial infrastructure or settlements on this map underscores the dynamic, water-dominated nature of the region. The presence of features like Shell Island Bay and Bastian Bay provides essential context for researchers tracking shoreline changes and coastal erosion in this fragile section of the Mississippi River delta.
