Marathon and the surrounding Middle Keys are depicted in this recent survey, capturing the modern infrastructure and protected waters of the Florida archipelago. The landscape is defined by the narrow corridor of the Florida Keys Overseas Heritage Trl and various local routes like Indies Dr N and W Seaview Dr that serve residential developments on Duck Key. The map reveals the intricate water passages critical to the region, including the Intracoastal Waterway, Toms Harbor Cut, and the Duck Key Channel, which separate the various keys and banks.
