Dry Tortugas National Park occupies the northern expanse of this maritime survey, a region where the Gulf of Mexico meets the Atlantic Ocean. The map captures the open water and navigational corridors of the Florida Keys' westernmost reaches, specifically documenting the Southeast Channel. As a modern record of these protected waters, the chart highlights the administrative boundaries of the national park against the vast nautical landscape of Monroe County. This specific area is characterized by its isolation and its role as a deep-water passage, reflecting the ongoing importance of precise hydrographic data for the preservation and navigation of this sensitive coral reef ecosystem.
