About this map

Alombro Cem sits as a solitary terrestrial landmark in a region dominated by the shifting hydrology of the Mississippi River Delta. This portion of the Barataria Basin, surveyed in 2020, reveals an intricate network of marshes and water bodies where the Barataria Bay Waterway serves as a primary navigational artery. The map details a complex transition from open water to interior marshland, featuring prominent estuaries like Bay Dosgris, Saint Joseph Bay, and Hackberry Bay.

Historically significant bayous such as Grand Bayou and Old Grand Bayou weave through the landscape, illustrating the natural drainage patterns of Jefferson and Lafourche Parishes. Names like Manila Bayou and Creole Pass reflect the cultural heritage of the coastal communities that have long navigated these wetlands. The topographic detail emphasizes the precarious nature of the land, defined by narrow ridges and expansive tidal basins.
