Dry Tortugas National Park encompasses the majority of this maritime survey, illustrating the critical intersection of protected wilderness and major nautical corridors in the Florida Keys. The map highlights the Southeast Channel, a primary passage for vessels navigating these waters, situated between the open expanse of the Gulf of America to the northwest and the Atlantic Ocean to the southeast. This 2025 edition provides an essential reference for understanding the modern maritime boundaries and hydrographic features of this environmentally sensitive region, where deep-water channels are the only lifelines for navigation through the reefs and shallows of Monroe County.
