2024 Map of Dry Tortugas OE S

About this map

Dry Tortugas National Park occupies the northern half of this coastal survey, where the shallow shelf of the archipelago meets the deeper waters of the open sea. The map documents a critical maritime boundary where the Gulf of Mexico and the Atlantic Ocean converge. Submerged features such as Bird Key Bank and the protected waters of Bird Key Harbor are clearly delineated, providing essential context for the reefs and shoals surrounding this westernmost part of the Florida Keys. Navigational landmarks like the Southwest Channel lead toward the Straits of Florida at the southern edge of the sheet. This recent USGS update offers a precise view of the park's marine boundaries and hydrographic features at the edge of the continental shelf.
