1958 Map of East Delta

About this map

Plaquemines Parish's shifting marshlands and deep-water channels are captured here during a period of intensive petroleum development at the Mississippi River's mouth. The map highlights the industrial imprint on this delicate landscape, featuring the Garden Island Bay Oil and Gas Field and the Freeport Sulphur Co Fresh Water Reservoir, essential infrastructure for the extraction economy of the mid-20th century. Maritime activity is anchored at the southern tip by Port Eads and the Pilot Station, serving vessels navigating the treacherous passage into the Gulf of Mexico. Beyond the industrial zones, the Delta Migratory Waterfowl Refuge and various State Public Hunting Grounds reflect a landscape managed for both conservation and sport. Numerous family-named and descriptive water bodies, such as John Johnson Pond and Horse Duck Pond, provide specific touchpoints for local history and genealogy.
