Chokoloskee Island: Shell Mound and History

What Chokoloskee Island is

Chokoloskee Island sits at the extreme southern edge of the Ten Thousand Islands, a roughly 150-acre patch of solid ground rising out of the mangrove flats where Chokoloskee Bay meets the open Gulf. It’s easy to miss on a map next to the sprawl of Naples and Marco Island to the north — this is a small, quiet fishing village, not a resort town — but it holds an outsized piece of Southwest Florida history. A short causeway across the bay connects it to Everglades City, the last real town before the Ten Thousand Islands give way to Everglades National Park’s roadless backcountry.

What makes Chokoloskee unusual isn’t its size. It’s what’s underneath it. The island isn’t a natural sandbar or a barrier key like the ones our boats run past near Marco — it’s built. Centuries of shell deposited by the people who lived here raised the ground nearly twenty feet above the surrounding mangrove swamp, turning a patch of tidal muck into the highest, driest real estate for miles. That’s the whole story of Chokoloskee in one sentence: a shell mound that became an island, that became a trading post, that became a town.

A shell mound built by hand, one generation at a time

Long before Ted Smallwood or Edgar Watson ever set foot here, the Calusa — and the Glades-culture people before them — built Chokoloskee up by hand, shell by shell, over centuries. Every oyster, whelk and clam eaten and discarded became part of the mound. It’s the same building technique you see at Mound Key up near Estero, once a Calusa capital, and it’s why so many of the solid, high-ground spots scattered through the Ten Thousand Islands and Everglades backcountry started life as kitchen middens rather than natural land. In a landscape that’s almost entirely mangrove and tidal flat at or near sea level, a twenty-foot shell mound was as close to a hill as this coast gets.

That elevation is exactly what made Chokoloskee livable centuries later. When pioneer families started working their way into the Ten Thousand Islands in the late 1800s, the mound gave them dry, stable ground to build a homestead on — something the surrounding mangrove islands couldn’t offer. You can still see the shape of it walking the island today: streets and yards that sit noticeably higher than the water around them, all of it built on ground the Calusa raised long before Florida was Florida. If you want to see a similar shell-mound key that’s stayed wild rather than becoming a town, our Dismal Key shell mounds page covers one further out in the refuge.

The Smallwood Store and the Edgar Watson saga

In 1906, Ted Smallwood opened a trading post on Chokoloskee’s waterfront, and it became the hub of the whole southern Ten Thousand Islands — a store, a post office, and the one reliable place to trade with the Seminole families who paddled in with hides, furs and egret plumes to swap for supplies. There was no road connecting Chokoloskee to anywhere for decades; everything and everyone that reached the store came by water. The building still stands on its original pilings, preserved today as the Smallwood Store museum, its shelves stocked much the way they’d have looked a century ago, and it’s listed on the National Register of Historic Places.

The store is also where Chokoloskee’s most famous — and darkest — story played out. Edgar J. Watson, a farmer with a violent reputation who’d worked land in the Ten Thousand Islands backcountry, was shot dead in front of the Smallwood Store in October 1910 by a group of his Chokoloskee neighbors, after suspicion spread that he’d killed several of his hired hands. The story became local legend almost immediately, and it eventually became literature: author Peter Matthiessen spent decades researching the Watson saga and turned it into an acclaimed trilogy — Killing Mister Watson, Lost Man’s River and Bone by Bone — later combined into the National Book Award-winning Shadow Country. If you’re curious where the legend continues, our Rabbit Key page covers a nearby island still tied to the Watson story.

Southern gateway to the Ten Thousand Islands

Chokoloskee doesn’t just look back at history — it’s also a literal gateway. The island sits right at the edge of the Ten Thousand Islands, at the mouth of Everglades National Park’s Wilderness Waterway, the roughly hundred-mile backcountry route that winds through mangrove tunnels and open bays all the way to Flamingo. Paddlers staging multi-day trips into that wilderness typically launch from Chokoloskee or the Everglades City side, and backcountry fishing guides run out of the same waters chasing snook, redfish and tarpon through the mangrove creeks — tarpon fishing here, like everywhere in Florida, is catch-and-release and regulated by season.

The Everglades Gulf Coast Visitor Center, just across the causeway in Everglades City, is the practical starting point for anyone planning to explore this end of the islands — it’s where you’ll find current backcountry permit information and ranger guidance before pushing off into the park. Our own Gulf Coast Visitor Center page covers what’s there. From Chokoloskee south and east, the shell-mound keys keep going — smaller, wilder, harder to reach — deep into water that sees far fewer boats than the stretch our captains run daily.

Visiting Chokoloskee today

Here’s the honest note: Chokoloskee is well south of Marco Island, out toward Everglades City on US 41, and it isn’t a stop on our regular shelling, dolphin or sunset routes out of Marco and Goodland. We cover it here because it’s the historical anchor for the whole region we run — understanding Chokoloskee’s shell-mound origins and the Smallwood Store era gives real context to every other key, bay and pass in the Ten Thousand Islands our boats actually visit.

If a visit to Chokoloskee itself is on your list, it’s a straightforward drive and worth pairing with a stop at the Smallwood Store museum and the Gulf Coast Visitor Center. And if what draws you to Chokoloskee is really the shell-mound history and the wild, roadless feel of the Ten Thousand Islands, you don’t have to drive that far to find it — our shelling tours and private charters run through the same kind of mangrove-and-shell-mound country closer to Marco and Goodland, and a custom private charter can be built around exactly the stretch of water you’re most curious about.
