About this map

Pointe aux Marchettes stands at the edge of the sprawling wetlands in Saint Bernard Parish where the marsh meets the open waters of Lake Borgne. This coastal landscape is defined by an intricate network of tidal channels and basins, including the West Branch Grand Bayou and South Branch Grand Bayou. Significant water bodies like Grand Lagoon and Brick Lagoon dominate the interior, illustrating the precarious and shifting geography of the Mississippi River delta region.

Evidence of human activity is found at the Bayou Biloxi Gas Field and near Magnolia Mound, highlighting the region's extraction industry and localized high ground. The southern portion of the map is traversed by Bayou la Loutre, a historic waterway that has long served as a corridor through the wetlands. Smaller channels such as Padre Bayou and Blind Bayou further reveal the complex hydrology that shapes this part of the Louisiana coast.
