The western edges of the Marquesas Keys are defined by shifting shoals and shallow harbors where the Gulf of Mexico meets the Straits of Florida. This 2012 survey details a treacherous maritime landscape west of Key West, dominated by the appropriately named The Quicksands and a series of navigational hazards including Rebecca Shoal and Isaac Shoal. The map reveals the intricate formation of the islands and tidal flats, showing the sheltered waters of Mooney Harbor protected by Mooney Harbor Key and the small Gull Keys. Unlike more developed coastal quadrangles, this map is almost entirely marine in nature, focusing on the submerged geography and the natural deep-water passage of the Rebecca Shoal Channel used by vessels transiting the Florida Straits.
