1967 Map of South Point

About this map

Lake Pontchartrain dominates this coastal survey, where the saltwater expanse meets the marshy fringes of St Tammany and Orleans Parishes. The industrial character of the gulf coast is evident in the presence of the Big Point Gas Field, marked across the open water. At the southeast edge, the small settlement of South Point provides a rare point of dry land, defined by local waterways like the Southern Canal and Irish Bayou Lagoon. This 1967 mapping, which includes photorevisions from the late 1970s, captures the complex hydrology of the region before significant modern development altered the shoreline. Tracing the Indefinite Boundary through the lake reveals the jurisdictional complexities of this aquatic landscape, while family-named features like Cane Bayou and Bayou Castiglione offer clues for those researching the local geography of the bayou country.
