2025 Map of Dry Tortugas OE E

USGS Topo · Published 2025

About this map

Fort Jefferson stands as the primary landmark on this maritime survey, situated on Garden Key within the expansive Dry Tortugas National Park. This 2025 USGS update illustrates the delicate geography of the lower Florida Keys, where small islets and hazardous shoals define the navigation of the Gulf of America and the Atlantic Ocean. The map charts several critical keys, including Hospital Key, Middle Key, and East Key, alongside treacherous underwater features like Pulaski Shoal and Bush Key Shoal. These low-lying features create protected waters such as Northkey Harbor, highlighting the complex reef system. The spatial relationship between Bush Key, Long Key, and the massive masonry structure of the fort underscores the strategic importance of this isolated archipelago, serving as a modern reference for the changing shorelines of these vulnerable coral islands.
