1970 Map of Perdido Bay

About this map

The boundary between Florida and Alabama runs through Perdido Bay, dividing a landscape of coastal lagoons and marshy inlets in 1970. On the Florida side, development is concentrated in areas like Gulf Beach Heights and Treasure Hill Park, while the barrier island of Perdido Key remains defined by the Old River and the sweeping sands along the Gulf of Mexico. The maritime infrastructure of the era is evident at the Holiday Harbor Marina and along the Intracoastal Waterway, which cuts through Big Lagoon. Inland, the terrain transitions into the Garcon Swamp and the protected waters of Tarkiln Bay. Local landmarks such as Red Bluff and Inerarity Pt mark the irregular shoreline, documenting the coastal geography before decades of modern expansion.
