Of Ice Worms and Men: Alaska’s Most Curious Cold-Loving Myth

A Tale Best Told at 40 Below

Alaska is a land of improbable stories. Some are worn smooth from generations of retelling, others half-whispered in passing at gas stations on the edge of the road system. And every so often, a tale comes along that’s too strange to be made up — and yet surely is.

Somewhere between scientific curiosity and Arctic folklore lies the story of the ice worm. It’s a tale best shared beside a stove that crackles against the hush of winter, in a cabin that’s a little too far from anywhere. The listener ought to be just cold enough to believe that something might be moving beneath the glacier.

Whether the creature exists as nature’s frozen joke or simply the fever dream of someone snowed in for too long, the ice worm has taken up residence in Alaska’s cultural permafrost — and shows no sign of thawing.

What on Earth Is an Ice Worm?

Let’s begin, as all earnest myths do, with something real. Mesenchytraeus solifugus, commonly known as the ice worm, is a true and measurable organism — a small, black, threadlike annelid, no longer than a paperclip. It lives in and under coastal glaciers, particularly those in southern Alaska. You’ll find no ice worms in Antarctica, and rarely any in literature outside regional biology journals and snowed-in trail memoirs.

The ice worm’s most intriguing feature is its extreme sensitivity to temperature. It thrives just below freezing — somewhere between 32°F and “should we even be out here.” Raise its environment even modestly, and it begins to break down, turning to mush like an abandoned popsicle.

These worms burrow in glacial ice, surfacing only at dawn and dusk. Whether this is due to the light, the temperature, or some older instinct passed down through frigid millennia, no one is quite sure. What is clear is that they are among the few multicellular creatures adapted to such a hostile environment. And for some, that is already strange enough.

But, as with all good Alaskan stories, someone had to take things further.

Tall Tales in a Tall State: How Alaska Made the Ice Worm a Legend

The moment science identifies something unusual, folklore tends to show up in a parka with a mischievous grin. Early gold miners and mountaineers were the first to encounter ice worms in the late 19th century. Many were unfamiliar with glacial terrain, and spotting a living creature squirming through solid ice had a way of unsettling even the hardiest prospector.

Some swore the worms only came out to dance under full moons. Others described the worms as sentient and musical, fond of gin, jazz, and pipe tobacco. There were claims of ice worms long enough to trip a sled dog team and clever enough to hide in a miner’s bedroll. None of these claims have held up under scrutiny — though they do make excellent campfire fare.

In Cordova, a small fishing town cradled between mountains and Prince William Sound, the annual Iceworm Festival was born in the 1960s. Originally designed to boost winter morale, the festival now features a 150-foot-long ice worm parade float, costumed mascots, and even themed cocktails (typically blue, invariably strong).

Ice worm mythology, like most Alaskan humor, walks a fine line between earnestness and deadpan absurdity. Locals tend not to correct outsiders who take the stories at face value. Some may even direct an unsuspecting tourist toward “ice worm mating grounds” if they seem the gullible type.

The Alaskan Wild: A Landscape Built for Belief

There’s something about the land itself that encourages tall tales. The vastness. The silence. The way clouds wrap around mountaintops like wool scarves pulled high against the cold. In places where the nearest neighbor is a hundred miles away — and possibly a bear — one begins to understand how a story could take root and grow unchecked.

Glaciers, in particular, are uncanny things. They creak and groan and sigh in the night. Their surfaces ripple with fissures that open like mouths. To walk on a glacier, especially alone, is to feel that you are stepping on something ancient and alive. If something strange were to crawl from its depths — a worm, say — it might not feel entirely out of place.

And then there’s the matter of access. Many of the glaciers where ice worms have been reported are remote, accessible only by helicopter, long hikes, or by those willing to brave the rough backcountry trails during a bout of ATV riding in Alaska — that peculiar blend of thrill, solitude, and engine-sputtering stubbornness that defines so much of the state's off-grid exploration.

There’s a story from a rider — one of those Alaskans who wears their machine like an extension of their will — who swore he caught something wriggling across the ice as he crested a ridge. He stopped the ATV, walked closer, saw the thing disappear into a hole. A worm? A trick of the light? He won’t say. He just laughed and drove on.

Beneath Alaska’s Ice: Can Science and Story Share a Sleeping Bag?

Science, naturally, is suspicious of romance. Ice worm research has revealed useful insights into how life might survive in extreme conditions — from Europa’s frozen oceans to Mars’ polar caps. They have been studied for their unusual proteins, their cold-adapted metabolisms, and their potential as analogs for extraterrestrial life.

Yet for all that science knows, it admits to knowing very little. The ice worm’s full range remains a mystery. Observing them is difficult; capturing them is trickier still. And because they die so quickly at warm temperatures, transporting them for study is almost impossible. The best observations often happen in situ, by researchers who are part scientist, part mountaineer.

Some biologists, when asked, will speak of the ice worm with a certain reverence. It’s the kind of reverence reserved for creatures that live in environments where humans cannot. There is a humility in confronting life that thrives where we barely survive — and in admitting that the full story may never be known.

One researcher, asked whether she believed all the ice worm legends, simply said: “There’s more under the ice than we understand. That’s enough for me.”

Let the Ice Keep Its Secrets

In the end, the ice worm occupies that slippery space between knowledge and wonder. It is both a measurable species and a reminder that the world still has room for mystery. Alaska, with its sharp edges and soft legends, is the perfect home for such a creature.

On a summer evening, when the sun hangs low but never sets, an ATV might rumble along the edge of a melting glacier. Dust rises. The trail winds higher. There, on the edge of everything, it’s not so hard to imagine something small and black wriggling just out of sight.

Perhaps it was there. Perhaps it wasn’t.

The best stories, like the best landscapes, don’t always need to be proven. They only need to be possible.

And in Alaska — where worms dance, snow sings, and the ice listens — anything possible is worth believing in.
