About this map

Sugarloaf Key and the surrounding Saddlebunch Keys dominate this maritime landscape in the lower Florida Keys during the late 2010s. The geography is defined by a complex network of mangrove-lined waterways and shallow sounds, including Lower Sugarloaf Sound and Similar Sound. Land use is concentrated along the corridor of Old State RD 4a, where residential developments like those on Sugarloaf Blvd and Bay DR interface with the saltwater environment.

Navigational hazards and features of the Atlantic Ocean are meticulously documented, including the Intracostal Waterway and Hawk Channel. Deep-water markers and shoals such as American Shoal and Maryland Shoal define the transition to the Straits of Florida. The map captures the intricate balance between coastal habitation and the surrounding marine ecosystem, evidenced by the numerous named channels like Saddlebunch Number Four Channel that facilitate movement between the keys and the open sea.
