About this map

Breton Island and its surrounding archipelago anchor this coastal survey, where the shifting sands of the Mississippi River delta meet the Gulf of Mexico. The landscape is dominated by the Breton National Wildlife Refuge and the Delta National Wildlife Refuge, protecting a complex network of bayous and ponds such as Spoonbill Bend, Lake Romere, and Blackbird Pond. Navigational markers like the Breton Island Light and Cubits Gap Main Pass Lt define the maritime routes through these tidal flats.

Energy infrastructure is a prominent feature of the mid-century delta economy, evidenced by the Romere Pass Oil and Gas Field and the underwater developments of Block 69 Oil Field. The engineered Mississippi River-Gulf Outlet Channel cuts across the sound, illustrating the massive hydrological interventions intended to facilitate commerce. For local historians, the named points and islands, including Harris Island and Japan Island, provide a detailed record of the delta's configuration before significant late-century coastal erosion.
