About this map

Mississippi River riverbanks define the narrow strip of habitable land in this 1970s orthophotomap of Plaquemines Parish. Traditional settlements like Ironton, Alliance, and St Rosalie cling to the levees, demonstrating the historical dependence on the river for transport and industry. Industrial footprints are prominent, including a large Refinery with its associated Conveyor and Elevated Pipeline systems transferring materials to and from the waterway.

Beyond the river-facing developments, the landscape transitions into the vast marshes of the Mississippi Delta. Features like Spanish Lake, Shell Bayou, and the Oak River reveal the complex hydraulic network of the region. Civil engineering works are evident through the Back Levee Canal and Wilkinson Canal, which represent the ongoing effort to manage the water and provide drainage for communities like Myrtle Grove and Wills Point.
