1971 Map of South Pass

USGS Topo · Published 1974

About this map

Port Eads stands at the tip of the Mississippi River delta, marking a critical transition between the river's South Pass and the open waters of the Gulf of Mexico. This 1971 orthophotomap reveals the intensive industrialization of the marshlands, where an extensive Oil and Gas Field and the Block 27 Oil Field are integrated into the fragile coastal ecosystem. A network of steam pipes, gas wells, and a large Fresh Water Reservoir enclosed by a Levee demonstrate the infrastructure required for extraction in this aquatic environment.
