Plantation Island isn’t an island, or is it?
Chokoloskee a little further off coast, on the other hand, is an island. It’s located in the background of the photo to the far left and pretty close to the mouth of the Turner River where it empties into Chokoloskee Bay. Chokoloskee is a shell midden that dates back to the coastal empire of the Calusa Indian Tribe that dominated south Florida in pre Columbian Times. Believe it or not, it’s maximum elevation is nearly a whopping 20 feet above sea level. That’s higher than most if not all of Naples. Up in 1953, Chokoloskee was a true island community. The only way to travel back and forth to the mainland was by boat. That changed with the construction of the Chokoloskee Causeway that provided an overland route (visible as a thin sliver in the photo above).
Compare that to Plantation Island that was built along the banks of Halfway Creek in or around 1968. How did Halfway Creek get its name? Answer: By merit of its location about halfway between Turner River (Chokoloskee) and Barron River (Everglades City). As for its height, my guess is its just a few feet above sea level, or a solid 10 feet lower than the island the Calusa built. And if you consider its surrounded by a creek and mangroves on all sides, despite being on the mainland I think its designation as an island holds up.
