About this map

Breton Sound dominates this coastal area in southeastern Louisiana, where the vast open waters meet the shifting marshland of the Mississippi River delta. The map illustrates the administrative boundary between St. Bernard Parish and Plaquemines Parish, which runs through the northern reaches of the sound. This aquatic environment is characterized by minimal terrestrial features, emphasizing the expansive nature of the Louisiana gulf coast's interior bays and sounds.

Mozambique Point stands as a primary landmark in the northwest, extending into the waters near Black Bay. The landscape represented here is defined by its lack of established infrastructure, reflecting a portion of the state where the environment remains dictated by tidal influence and shoreline erosion. This survey provides a precise reference point for the parish lines as they existed in the early twenty-first century.
