2024 Map of Dry Tortugas

About this map

Loggerhead Key and the surrounding waters of the Gulf of Mexico define this aquatic landscape within the Dry Tortugas National Park. This maritime chart highlights the complex underwater topography of the Tortugas Bank, where depths and shoals dictate the flow of the sea. Navigational features include the Northwest Channel and several significant hazards to mariners, such as Smith Shoal, Brilliant Shoal, and White Shoal. The map serves as a contemporary record of these sensitive island and reef environments in Monroe County, documenting the isolation and structural character of the westernmost extent of the Florida Keys.
