2018 Map of Marquesas Keys East

About this map

The Marquesas Keys form a distinctive circular atoll-like formation in the Florida Keys, with this eastern portion of the group revealing the sheltered waters of Mooney Harbor. Situated where the Atlantic Ocean meets the Straits of Florida, the map documents the shifting shorelines of these carbonate islands as they existed in the late 2010s. To the east, the isolated Boca Grande Key stands alone, separated from the main Marquesas group by the deep passage of the Boca Grande Channel. The lack of roads or infrastructure on this sheet emphasizes the preservation of this maritime wilderness, providing a precise record of the natural sand and mangrove distribution across these remote outposts west of the inhabited Keys.
