Chokoloskee

Shell mounds are the signature of the Calusa, the people who ran this coast when the Spanish arrived and who built a complex society on fishing rather than agriculture. They did not farm maize and they did not need to; the estuary produced enough.

What they left behind is structural. Over centuries of occupation the discarded shell built up into raised platforms that supported houses, ceremonial structures and, eventually, whole communities. Chokoloskee is one of the largest surviving examples in Southwest Florida. Estimates put the beginning of the mound's accumulation well over a millennium ago, and some of the island's height is many metres of shell.

You cannot dig into it or take shell from it, and the island's archaeology is not presented as a site with a trail and interpretive boards. What you can do is notice the elevation as you drive in — a genuine slope, in a landscape with nothing else like it for thirty miles — and understand that you are driving up something people made.

The mound's height is also why the settlement survived storms that removed communities elsewhere on this coast, and why the Smallwood Store, raised further on pilings, is still standing after a century of hurricanes.

For eighty years Chokoloskee had no road. Supplies, mail, post and passengers came by boat from Everglades City and from Fort Myers, on a schedule that the weather routinely overruled. Families here were used to a level of self-sufficiency that is difficult to imagine from a rental car.

That ended in the mid 1950s when a causeway was built across the bay from Everglades City — the exact year is given as 1955 in some accounts and 1956 in others. Whichever it was, it changed everything: a truck could now reach the island, and the community stopped being an island in the practical sense while remaining one on the map.

The causeway was replaced in August 2018 by the Chokoloskee Bridge, higher and wider and built to modern standards. That upgrade looked like ordinary infrastructure spending at the time. Four years later Hurricane Ian went through, and having a higher, stronger crossing to the only inhabited high ground for miles looked like foresight.

SR-29 ends at the island's southern edge. There is no onward road, no ferry and no route further south. Everything beyond is water and mangrove, all the way to Cape Sable.
