1947 Map of Rock Harbor

About this map

Key Largo stretches across this mid-century survey, showcasing the early development of the Upper Keys along the Overseas Highway. This map documents a transitional period for the islands, where the western shoreline meets the Everglades National Park and the eastern edge opens to the Atlantic Ocean. Local life is anchored by small settlements like Newport and Thompson, with community landmarks such as St Margarets Ch and Gethman Memorial Ch serving as focal points for the growing population.
