1994 Map of Dog Island

About this map

Dog Island stands as a distinct barrier between the Gulf of Mexico and the protected waters of Saint George Sound in this 1990s bathymetric-topographic study. The map documents a landscape defined by shifting sands and maritime access, featuring the small Dog Island Airstrip and the sheltered basin of Tysons Harbor on the island's leeward side. Beyond the land, the survey provides extensive underwater depth contours, noting that much of the surrounding seabed is an area subject to frequent change. To the north and east, the protected waters of the Alligator Harbor State Aquatic Preserve and the long stretch of Lanark Reef illustrate the complex coastal ecology of Franklin County before the turn of the twenty-first century. A Ferry route connects the island to the mainland, emphasizing its isolation and reliance on waterborne transport.
