Sturgeon Swimming in the Apostle Islands May Be Older Than Wisconsin Itself.

The lake sturgeon cruising the bottom of Lake Superior and Chequamegon Bay have always looked prehistoric. New research says some of them come close.

A study published in the Journal of Fish Biology by the Michigan Department of Natural Resources and Michigan State University finds that lake sturgeon can live 200 years or more, with some individuals approaching 300. That places them among the oldest freshwater fish in North America, in the same conversation as the Greenland shark.

The old method for aging a sturgeon was counting growth rings in a fin spine, the way you would read a tree stump. It works fine on a young fish. On an ancient one the rings crowd together until they blur, and researchers suspected they had been badly undercounting the oldest animals. So Scott Colborne and his team went at it differently. They pulled one of the largest long term datasets ever assembled for the species, growth records from tagged fish measured again and again over years, and ran the same mathematical models used to estimate the age of Greenland sharks.

The numbers came back much bigger than expected.

A sturgeon at the far end of that range would have been alive when the Boston Tea Party happened. It would have been swimming when Lewis and Clark headed west, when Wisconsin became a state, and when the Edmund Fitzgerald went down. Indigenous communities have long held that sturgeon live as long as 400 years. Modern statistics were catching up to knowledge that was already here.

The conservation math matters more than the trivia. Sturgeon mature slowly and spawn infrequently. A population knocked down by overharvest and dam building does not bounce back in a season or a decade. If the fish live twice as long as anyone assumed, then every survival estimate, every harvest model, and every habitat restoration scorecard needs a second look.

Give them the chance, Colborne said, and they will figure it out. They have been doing it for millions of years.

APOSTLE ISLANDS SEA CAVE KAYAK TOURS, BAYFIELDKAYAK.COM
Here is what nobody tells you before you book an Apostle Islands sea cave kayak tour.
THE CAVES, FROM EASIEST TO HARDEST
Chequamegon Bay (Bono Creek). Easiest. 2 miles round trip, 4 sea caves. The bunny hill, perfect for young kids, first timers, and dogs. Even the bunny hill here beats anything at Red Cliff or Madeline Island.
Houghton Point. Easy to intermediate. 3 miles round trip, 5 sea caves. The most reliable conditions in the islands. These protected east side tours keep running into October and November, long after the west side shuts down.
Roman's Point. Intermediate. 3 miles round trip, 5 sea caves, including two tunnel caves over 100 feet long where you paddle in one side and glide out the other, plus the most photogenic sea arch in the Apostle Islands, towering 50 feet over the water. No crowds in your shot. Never heard of it? For a decade an unlawful local ordinance blocked every outfitter but one from launching here. A judge has ruled it unenforceable. The monopoly is over.
Meyers Beach. Advanced. 4 miles round trip with a small group outfitter, up to 8 miles with the big ones. The best sea caves in the islands, full stop, but it is crowded, so a tour realistically gets you into about 6 of them. The big outfitters jam 21 person groups behind first year guides reading a script. When 21 people hit the same cave at once, it stops feeling like Lake Superior and starts feeling like standing in line.
Sand Island. Advanced. 4 miles round trip, 6 sea caves, and some are interconnected, so you paddle into one and discover passages into others. It paddles more like 8. Go small group or do not go.
WHO TO BOOK WITH
Beginners, kids, and dogs: Bayfield Kayak (bayfieldkayak.com) and Paddle Ride Adventures (kayakingapostleislands.com). The only outfitters running the east side caves, with the lowest cancellation rates in the islands. Bayfield Kayak (bayfieldkayak.com) also runs Roman's Point for intermediate paddlers.
Meyers Beach and Sand Island: Stevie Waters (steviewaters.com) and Wisconsin Paddle (wisconsinpaddle.com). Small local businesses, groups of 12 or fewer and often 6 or fewer, ACA certified, with lead guides who have years on this water and real answers to your questions.
THE TOURS TO AVOID
Not everything sold as a sea cave tour is one. Red Cliff has one collapsed sea cave and one small sea arch, and that is the extent of its sandstone features. Madeline Island is just as underwhelming: two sea caves so small you can hardly fit a kayak inside, sold as a sea cave tour to a captive audience they know has no other options once they are out there.
THE CANCELLATION TRAP
Meyers Beach cancels about half the time. Big outfitters will push you to another day or haul you to Bark Bay Slough, a marsh with zero sea caves. You paid for sea caves and got a swamp. The four outfitters above all run real caves on the protected east side, so a cancellation means a genuine sea cave alternative with the price difference refunded, or your money back.
The best tour is not the company running the most kayaks. It is the outfitter that gives you the right location, the right guide, and enough room to actually experience it.
Now through the end of September is your shot, and August is the sweet spot, with the lowest winds of the year on the west side of the peninsula. Ask a local and they will tell you late August into early September is the best paddling of the entire year.
