1970 Map of Point Au Fer

About this map

Point Au Fer Island sits at the volatile threshold of Atchafalaya Bay and the Gulf of Mexico, a coastal landscape defined by shifting marshlands and tidal channels in 1970. This survey captures the region's mid-century industrial character, dominated by the Locust Bayou Oil Field and a complex network of pipelines and canals carved through the wetlands. The coastline is marked by distinctive features such as Point Au Fer Shell Reef and Dead Alligator Point, reflecting both the biological and geological history of the Louisiana coast. Small rises in the marsh, notably Little Hammock and Narrow Hammock, provide rare relief in an area otherwise governed by the flow of Locust Bayou and Alligator Bayou. Further offshore, the presence of a lighthouse and radio tower on Eugene Island signals the importance of this stretch of water for navigation and coastal monitoring.
