s up to tall occur on the island. Anclote Key has lengthened considerably since 1960, especially on the northern end. This growth has blocked the channel at the north end of the island. In the 1990s sand bars developed off both the north and south ends of the island, blocking the shallow tidal channels there. Both shoals grew and emerged above water. The new islands are now vegetated, and are known as North Anclote Bar and South Anclote Bar, respectively. The area around Anclote Key had little sand available for deposition on shoals and barriers in the middle of the 20th century. There was sand on the Gulf bottom, but it was anchored by beds of
