About this map

Everglades National Park encompasses the vast majority of this maritime environment, where the shallow waters of Florida Bay meet the open Atlantic Ocean. The landscape is defined by a scattering of mangrove islands and submerged banks, including the central Upper Arsnicker Keys and Lower Arsnicker Keys. These features serve as critical navigational markers and ecological habitats within the protected park boundaries.

Navigational routes are prominent in the southern reach of the map, specifically the Intracoastal Waterway, which cuts through the shoals near Buchanan Bank. The intricate network of named shallows, such as Ninemile Bank and Arsenic Bank, reveals the complex bathymetry of the keys before they transition into deeper ocean waters. This coastal survey documents the enduring geography of the Buchanan Keys and their surrounding marine features during the early twenty-first century.
