In a gas station in Fairbanks or a grocery store somewhere along the Parks Highway, a small paper ticket and a pen sit by the register, and somebody is quietly working out the exact minute a river will give way. That is the Nenana Ice Classic, Alaska’s long-running spring guessing game about the Tanana River. Visitors can take part if they are in the state while tickets are on sale, and they can also simply follow the contest from afar.
What is the Nenana Ice Classic?
The Nenana Ice Classic is an annual ice pool held in Nenana, Alaska, where people try to guess the exact time the ice on the Tanana River will break up. It is a lottery in spirit: you buy a ticket, you write down a date and a time in April or May, and you wait for the river to decide. There is no skill in the strict sense, only a mix of local lore, weather watching and hunches.
It is also a charity. The Nenana Ice Classic is a non-profit charitable gaming organization, and its proceeds benefit many volunteer and non-profit organizations. That gives the whole thing a different feel from a casino game. People buy a ticket partly for the thrill and partly because the money goes back into community groups.
Where the story begins
Nenana sits at mile 412 of the Alaska Railroad, so the tale fits the town’s identity as a railroad community. The surveyors spent a long winter waiting on the ice, and a wager on the thaw was a natural way to pass the time.
Another account places the first ice betting pool earlier, in 1906, with six entries and a first winner named Oliver Lee. Either way, the contest grew from a handful of bettors into a statewide habit. Since the beginning, well over ten million dollars in prize money has been paid out, a figure that shows how far a small riverside bet has traveled.
The town and the river
Nenana is a small city that incorporated in November 1921, and it sits on the Tanana River at an elevation of 351 feet. It is 55 road miles southwest of Fairbanks on the George Parks Highway, and 304 road miles north of Anchorage. The place covers a modest patch of land and water, and the river is plainly the main character.
The climate there is a transitional humid continental and subarctic mix, with long, cold and dry winters and warm summers with cool nights. That is exactly the setting for a river that freezes solid for months. The Tanana usually freezes between October and November, so a visitor in the fall is watching the river on the edge of its winter.
The most recent result
| Item | Detail |
|---|---|
| 2026 jackpot | $144,749 |
| 2026 winners | Joe Dinkins and Marie Thies, both from Fairbanks, Alaska |
Both winners come from Fairbanks, which makes the result feel like a local story, though tickets are sold across Alaska. The size of a jackpot depends on how many tickets people buy in a season, so each season’s pool stands on its own.
How does the contest work?
The contest works by measuring the moment the river ice moves, using a tripod planted on the ice and wired to a clock. Everything else is simply the guess you make before it happens. The physical setup is wonderfully low-tech, which is a large part of its charm.
The tripod and the clock
The tripod is planted on the river ice between the highway and railroad bridges in Nenana, 300 feet from the shore. A line runs from the tripod to a clock on the bank. As long as the ice holds, the tripod stays put and the clock keeps running.
When the ice finally goes out and carries the tripod a distance of 100 feet, the line breaks and stops the clock. The time on that clock is the official moment of breakup. Because the setup relies on the ice actually moving, a crack or a slow melt does not count, only the real departure of the river’s cover.
When the ice tends to go out
The river reaches its thickest point in early April, and then the long slide toward breakup begins. Melt records give a sense of the range, and the most common time of day is the afternoon. Anyone choosing a guess is really picking a point within that spread.
| Ice fact | Detail |
|---|---|
| Average peak thickness on April 1 | 41 inches |
| Earliest melt date through 2026 | April 14 |
| Latest melt date through 2026 | May 20 |
| Most common melt time | Between noon and 4:00 PM |
Those records show why the game is hard. The window runs for more than a month, and the answer is a single minute. A cold spring pushes the breakup later, a warm spell pulls it earlier, and nothing guarantees the pattern will hold.
Watching it live
A live webcam of the Tanana River for the contest is provided by Borealis Broadband. It lets people far from Nenana watch the tripod and the ice, which turns the final weeks into a kind of shared vigil. Many entrants check in often as their chosen date approaches.
The river is ice-free from early May to late October, so the tripod’s season is one of winter ice. By the time the water is open, the contest is over for that spring and the town returns to ordinary river life.
Can visitors take part?
Yes, visitors can take part as long as they are adults and are in Alaska while tickets are on sale. Tickets are sold throughout Alaska during a fixed window each spring, and there is no sign that you must live in Nenana or in the state to enter. The rules that matter are the age, the price and the dates.
| Item | Detail |

| Ticket price | $3.00 |
| Ticket sales window | February 1 through April 5 each year |
| Minimum age | 18 years |
| Where tickets are sold | Throughout Alaska |
Timing your trip
Because the sales window falls in late winter and early spring, a summer or fall visitor will find the contest closed. Right now, with the river still open and winter not yet arrived, the tickets for the next season are months away. A traveler planning a visit between February and early April is the one who can walk in, buy a ticket and make a guess.
The guess itself is a date and a time in April or May. Looking at the melt records is a fun way to choose, even though the result is never certain. People simply pick a birthday or a lucky hour.
Visiting Nenana itself
A visit to the town puts you beside the river that decides the contest. Nenana lies along the George Parks Highway, and the Alaska Railroad passes through it at mile 412. The tripod stands between the highway and railroad bridges, so those two crossings frame the spot where the story plays out.
Seeing the river in October, with the first ice not yet formed, gives a sense of how much changes before the spring contest begins. Following the webcam in spring is the other way to feel part of it, especially if you hold a ticket and have a date in mind.
Good to know before you go
The contest is a charity pool, so a small ticket is a small donation as much as a bet. Prize amounts change from one season to the next, and the winning pool in recent years has been well above the 2026 figure.
Nenana’s winters are long, cold and dry, and its summers are warm with cool nights, so dress for the season you visit in. The river is a working landscape, and the ice is the contest’s business, not a place for visitors to wander.
