The waters of the Gulf of Mexico dominate this 2012 chart of the southernmost reaches of Plaquemines Parish. This maritime landscape is defined by the shifting deltaic environment of the Mississippi River mouth, where coastal passes such as Pass Du Bois and Pass La Graisse provide critical channels through the marshy wetlands. These waterways have historically served as the primary transit routes for those navigating the edge of the continent. Industrial activity is represented by the Block 54 Oil and Gas Field, highlighting the economic importance of offshore energy extraction in this region. To the east, the expanse of West Bay underscores the precarious balance between the land and the rising sea in one of the most dynamic coastal zones in the United States.
