Lake Pontchartrain dominates this coastal landscape, illustrating the vast aquatic boundary between the northern and southern parishes. The aquatic expanse is framed by the Big Branch Marsh National Wildlife Refuge to the north and the Bayou Sauvage National Wildlife Refuge at the southeastern edge, highlighting the preserved wetlands essential to the region's ecology. In the lower right corner, the settlement of South Point sits near the confluence of the Little Woods Canal and Bayou Castiglione, where the land begins to break into the marsh. This 2024 map documents the modern parish line dividing St. Tammany Parish and Orleans Parish, tracing a path directly through the water. It provides a clear record of the intersection between managed federal lands and the edges of the New Orleans metropolitan area.
