1971 Map of South of South Pass

USGS Topo · Published 1974

About this map

South Pass serves as the focal point of this coastal orthophotomap, where the Mississippi River delta meets the open sea. This 1971 record highlights the industrial presence of the Block 27 Oil Field, with several offshore Platform locations identified across the deep blue waters. Along the narrow strip of land at the delta's edge, the East Jetty and various Light markers guide maritime traffic through the shifting channels. The northeastern corner of the map covers a portion of the Pass A Loutre State Waterfowl Management Area, showing the delicate balance between energy extraction and conservation in the Gulf of Mexico. The presence of an Indefinite Boundary reflects the constantly evolving nature of the Louisiana shoreline and submerged lands during the early 1970s.
