About this map

Martello Castle stands as a historic sentinel at the edge of Lake Borgne, marking a coastal landscape defined by shifting marshlands and industrial intervention in the late 1960s. This survey illustrates the significant impact of the Mississippi River - Gulf Outlet Canal as it carves through the wetlands of St. Bernard Parish. Large Spoil Areas line the canal, reshaping the natural hydrology of local waterways like Shell Beach Bayou and Bashman Bayou.

The map reveals the intersection of Louisiana's traditional coastal ecology and mid-century infrastructure. While the St Bernard High Sch and a series of Levee systems and Floodgates indicate established community life to the southwest, much of the quadrangle is dominated by a complex network of bayous, including Bayou Mercier, Terre-Beau Bayou, and Grand Bayou. Evidence of resource extraction is present through several Drill Holes and prominent Pipelines crossing the marsh.
