1970 Map of Point Au Fer NE

About this map

The Lower Atchafalaya River dominates this coastal landscape, where it empties into the vast waters of Atchafalaya Bay. This 1970 survey documents a complex network of marshland and maritime infrastructure, including numerous Drill Holes and pipelines that indicate active mineral exploration in the tidal zones. Along the northern edge, a series of inlets including Little Hog Bayou and Little Bay shape the shifting shoreline of Shell Island. The map is particularly valuable for its depiction of the St Mary Parish and Terrebonne Parish Indefinite Boundary, tracing a political line through the fluid geography of the bayou. To the east, the terrain transitions into the wetlands of Deer Island and Plumb Island Point, separated by the winding Deer Island Bayou.
