Dry Tortugas National Park dominates this maritime survey, illustrating a critical aquatic boundary where the Gulf of Mexico meets the Atlantic Ocean. The map centers on the open waters of the Southwest Channel and the Straits of Florida, documenting the nautical environment as it appeared in recent years. This specialized hydrographic record provides researchers with the precise jurisdictional limits of the national park within Monroe County. Because the area consists entirely of open sea and submerged features, there are no land-based contours, highlighting the map's role in tracing the maritime geography and protected marine zones of this isolated Florida keys region.
