1947 Map of Rock Harbor

About this map

Key Largo's narrow profile dominates this mid-century coastal survey, capturing the island during a period of rapid residential expansion as shown by extensive street grids and canal developments. The settlement of Rock Harbor serves as a central point of activity, flanked by smaller hamlets like Newport, Thompson, and Sawyer. Religious life is anchored by St Margarets Ch and Getman Memorial Ch, providing clear landmarks for local genealogical research. The geography is defined by the contrast between the protected waters of Buttonwood Sound and the open Atlantic Ocean. To the northwest, the boundary of Everglades National Park encompasses the Swash Keys and Florida Bay, while the Intracoastal Waterway cuts a straight line through the flats, marked by a series of beacons and lights to guide maritime traffic through Baker Cut.
