2024 Map of Marquesas Keys East

About this map

The Marquesas Keys form a distinctive atoll-like island group west of Key West, surrounded by the protected waters of the Key West National Wildlife Refuge. This maritime landscape is defined by the shallow waters of Mooney Harbor and the deep Boca Grande Channel, which separates the main atoll from Boca Grande Key to the east. The entire land area is managed as part of the Florida Keys Wilderness, ensuring the preservation of the small mangrove islands like the Gull Keys. Positioned between the Gulf of Mexico and the Straits of Florida, the map illustrates a dynamic environment where the Atlantic Ocean meets the subtropic keys, providing a detailed record of shoreline geometry and reef-edge boundaries essential for understanding the natural history of this uninhabited archipelago.
