2025 Map of Shark River Island

About this map

Everglades National Park covers the vast majority of this coastal reach, where the freshwater systems of The Everglades meet the salt waters of the Gulf of America. The coastline is defined by a complex network of tidal waterways and mangrove-lined shores, including the outlet of the Little Shark River and the meandering path of Big Sable Creek. Standing out as rare topographic landmarks in this low-lying wetland environment are the Shark River Island and the elevated ground of Shark River Bluff. This modern survey illustrates the current shoreline geometry of Cape Sable, providing a precise baseline for researchers studying the evolving hydrology and coastal morphology of South Florida's protected wilderness. The map also charts the expansive Ponce de Leon Bay, a critical interface for the region's estuarine ecosystems.
