1967 Map of South Point

About this map

Lake Pontchartrain dominates this coastal survey, where the aquatic boundary between St Tammany Parish and Orleans Parish runs through the open water. The map documents an era of offshore extraction, centered on the Big Point Gas Field and its related infrastructure. Along the northern shoreline, coastal geography is defined by Point Platte and Point du Chien, while the southeastern corner reveals a more intricate landscape of wetlands and inlets. Here, the settlement of South Point sits near the marshes of Irish Bayou Lagoon, providing a detailed look at the interface between the tidal waters of Little Cane Bayou and Bayou Castiglione. The inclusion of updated data from the late 1980s reveals the shifting nature of these wetlands at the edge of the New Orleans metropolitan area.
