About this map

Key Largo stands at the heart of this coastal study, showing the upper Florida Keys during a period of transition as development pushed south. The Overseas Highway threads through the island chain, crossing Cross Key and spanning Jewfish Creek to connect the mainland with these subtropical outposts. Much of the western waters and islets, including Shell Key and Boggy Key, are preserved within the boundaries of Everglades National Park, showcasing the intricate system of mangrove keys and sounds that define the region.

Coastal communities such as Anglers Park and Stillwright Point appear along the shorelines of Blackwater Sound and Largo Sound. These settlements, alongside Sexton Cove, reflect the mid-century growth of the Keys as a destination for maritime recreation and residential expansion. The map also delineates the complex waterway network through Tarpon Basin and Little Buttonwood Sound, where the shallow bays and tidal passes create a mosaic of land and sea.
