1979 Map of Southwest Pass

About this map

Burrwood serves as the primary outpost on this narrow strip of land extending into the Gulf of Mexico. Situated at the tip of the Mississippi River delta, this area is defined by its strategic maritime and industrial infrastructure. The map illustrates the complex system of stone and concrete works designed to keep the shipping lanes open, including the West Jetty and multiple structures along the East Jetty. To maintain commerce, the Southwest Pass Entrance is carefully monitored to ensure deep-draft vessels can navigate from the open sea into the river system.
