The ice has gone out on the Tanana River in Nenana, Alaska. Officially, the tripod moved enough downstream to trip the clock at 12:50 AST on April 30. The jackpot for the 2021 Nenana Ice Classic is $233,591.

The ice went out on the Tanana River at the village of Nenana on Monday. The tripod officially moved the distance to trip the clock at 1:56pm.
This was the second time that I have guessed the correct day the ice went out. I was so close, so tantalizingly close. As they say, close only counts in horseshoes and bear encounters.
Between the years of 1917 and 1989, the ice went out this early only three times. Since 1990, the ice has gone out this early 11 times.
Ice Classic officials say it may be a month before winners are notified and announced. They are running a skeleton crew due to Corvid-19. They have also stated that the number of tickets sold are well below normal numbers due to the difficulty after the virus forced businesses to close.

Not surprisingly, even the 103 year old Nenana Ice Classic has seen some changes this year due to Covid-19. Every year, since 1917, Alaskans have been betting on when the ice would go out on the Tanana River at the village of Nenana.
The earliest the ice has gone out was last year, when the famed tripod tripped the clock at 12:21 am on April 14. The latest the ice has gone out was on May 20, which has happened twice.
As one can see from the above graph, 2019 was an anomaly for more than one reason. The ice rarely goes out between midnight and 9am.
As of April 6, ice thickness near the tripod was 32.5″. Usually, all guesses/tickets must be in before April 6, but the deadline has been extended to April 10. We usually buy the tickets at various venues that have the bright red Ice Classic Can on their counter, the filled out tickets are then dropped in the can. This year, since so many businesses are closed, and people are urged to stay at home, guesses can be mailed to the Nenana Ice Classic directly. Entries must be postmarked no later than April 10, 2020. Each guess/ticket is $2.50.
I have never missed an Ice Classic since I moved to Fairbanks, and this year joined the stay at home club, and mailed in my guesses. Last year’s jackpot was $311,652.

The Fairbanks North Star Borough has recently proposed dismantling the historic sternwheeler.
I knew something was up. Several contractors I’ve talked with were willing to donate time & resources to the ship’s restoration, which would be added to grants and fundraising, but the Borough was obviously stalling, and we were convinced they just wanted to look the other way until nature takes over.
In all honesty, Fairbanks is terrible when it comes to valuing its history. Fairbanks has only existed since 1904, so its not like it’s an overwhelming time frame.
So for my readers in Fairbanks, drop the Borough Assembly an email if you’d like to see the Nenana remain the centerpiece of Pioneer Park. Don’t hold your breath for a response. Of the nine members plus the mayor, only two bothered to respond to my inquiries.
An Assembly meeting on the subject is slated for January 16.

The Mears Memorial Bridge was completed on 27 February 1923. The 700 foot long truss bridge spans the Tanana River at Nenana, Alaska. The bridge was the final link in the Alaska Railroad.
The bridge is named after Colonel Frederick Mears, the chief engineer and chairman of the Alaska Engineering Commission, the builder of the railroad and its original operator. In 1923, the Mears Bridge was the longest truss span in the United States and its territories. It spans the longest distance of any bridge in Alaska, and is still the third longest simple truss bridge in the U.S..
The monthly ice thickness check on the Tanana River took place recently for the month of February. I find this fascinating, so don’t be surprised if I post the March report too.
For most years, the ice thickness can run around 40 inches in February. Even after a week of -30F weather, and lows in the -44F range, there was no change in ice thickness from January. The Tanana River still has 16 inches of ice above the flowing water.
The earliest date on record for the ice to go out on the Tanana is April 20, which happened twice: 1940 & 1998. It certainly looks like that record could be on thin ice.
I received a request for more behind the ice information regarding the Classic.
In 1906, six gentlemen bet on the date the ice would go out on the Tanana River. The contest returned in 1917, when railroad engineers bet $801 on the date. The contest has been held every year since then, and has become an Alaskan tradition.
The tripod, is technically a quad pod. It’s made out of local logs and weighs several hundred pounds. A trough is dug in the ice for the tripod base to sit in, then a hole is bored through to allow river water to fill the trough and freeze the base in place.
Now things get really cool, but keep in mind the system was designed by railroad engineers in the early 1900’s.
A cable is fastened to the tripod, and four ropes run from the cable to a tower on the shoreline. The main rope runs through a pulley system that connects to a barrel weighted with several hundred pounds of rocks at the base of the tower. When the ice starts to move, this rope takes all of the stress and lifts the barrel of rocks several feet into the air.
A second rope has a foot of slack. This one triggers a siren in the town of Nenana to signal that the ice has started to move.
The third rope runs to a cleaver. This one has a bit more slack. The cleaver has been weighted, and also has over the years gained the nickname “Eldridge”. Named after the one time Black Panther leader, Eldridge Cleaver. However, Fred Mueller of Nenana, who designed this elegant system way back in the day, said he received his inspiration for the cleaver from the guillotine.*
When the tripod moves 100 feet, the rope to “Eldridge” pulls a pin, the cleaver is released, cutting the main rope. The counterweight crashes to the ground, and the tripod is free to float down the river.
Once the main rope is cut, it falls pulling the final line, which is attached to a copper wire on the clock. The clock is then tripped, after the tripod moves 100 feet downstream, signifying the winning time.
There are actually two mechanical clocks. The one pictured here, which is a ship’s chronometer, was manufactured by the Elgin National Watch Company – which stopped making clocks in 1967 – needs to be wound once a day. The second, back up clock, needs to be wound only once every eight days.

Tickets are now on sale for the 2019 Nenana Ice Classic. Buy a ticket, guess the date & time the ice will go out on the Tanana River, moving the iconic tripod, and win Alaska Glory, along with a dollar or two. Last year’s jackpot was $225,000.
Please note, all times must be Alaska Standard Time; tickets are on sale throughout Alaska through April 5th. Participants Outside must contact the Nenana Ice Classic directly for purchase.
Last year I was exactly three hours late with my guess. You’d think the damn Tanana could have held on for three hours!
Nenana Ice Classic officials announced the ice thickness of the Tanana River recently. It was the thinnest ice ever recorded on the Tanana in January. To be fair, the Nenana Ice Classic contest may be over 100 years old, but officials only started announcing the ice thickness back in 1989.
January ice thickness usually falls between 30 and 45 inches in January. In 2019, the thickness was only 16 inches. The previous low was 21.5″ in 2004.
The Tanana River froze over in October, which is normal, but we had such a mild first half of the winter, that the ice has not thickened to normal levels. That is the case for rivers throughout Interior Alaska right now. River travel has been sketchy in spots.
The annual Nenana Ice Classic is Alaska’s longest running game of chance. Every year we guess the date & time the ice “goes out” on the Tanana River. Tickets for the 2019 event go on sale February 1.
The SS Nenana is a steam powered, sternwheeler that was originally commissioned by the Alaska Railroad in 1932 for their Steamboat Service. Her parts were built in Seattle, then shipped north to Nenana, Alaska and assembled there. Named for the community where she was built, the SS Nenana first entered service in 1933.
The Nenana has five decks: cargo; passenger or saloon deck; boat deck, which housed the life boats; the Texas deck, which had cabins for the captain, crew and any VIP travelers, and topped off with the pilot house.
At 237′ long and 42′ wide, the Nenana had 22,000 square feet of deck space. She was built to handle passengers and freight, housing up to 50 passengers in 24 staterooms, and could haul 300 tons of cargo. A full load usually had a crew of 32 and a passenger list of 35. Completely loaded, the Nenana drew only 3’6″ of water.
From 1933 – 1954 she ran the Tanana & Yukon Rivers from May through September. Her main route was between Nenana and Marshall, which was 858 miles. The Nenana had one of the most advanced power systems of its time: twin, tandem 330 HP horizontal condensing engines. The engines could recycle 85% of the steam back into water, allowing the Nenana to be surprisingly quiet. She was powered originally by burning wood, and could store 230 cords of firewood on board. In 1948, the Nenana was converted to burn oil.
While traveling the Yukon River, the Nenana could push up to 6 barges. On the Tanana River, she was limited to only one barge, due to that river’s sharp turns.
During WWII, the Nenana was a vital part of the war effort. Between the massive military buildup within Alaska, and as aircraft and other equipment was ferried across the state on its way to Russia, the Nenana moved supplies for Galena Air Base and a host of other military outposts scattered along the Yukon River Basin.
By 1955, the SS Nenana was pushed out of the freight and passenger business by cheaper and faster means of transportation. Her story doesn’t end quite there, however.
