FAIRBANKS—The Nenana Ice Classic tripod is down.

The tripod had been teetering but didn't stop the clock until it moved sufficiently downstream Tuesday and one of the attached lines tripped the clock at 2:18 p.m. Alaska Daylight Time, meaning the winning ticket time is 1:18 p.m. Alaska Standard Time.

The tripod, perched on the Tanana River, tipped a day earlier and set off the alarm at the Nenana Ice Classic guard tower, but the tripod didn't travel the 100 feet downstream necessary for one the lines from the tripod to pull a pin, which then would let a meat cleaver fall and cut the wire to stop the analog clock.

The jackpot this year is $225,000. Ice Classic officials will announce the winner or winners once they are able to get all the tickets sorted.

The Nenana Ice Classic is Alaska’s oldest guessing game. It began in 1917 as a bet among railroad engineers waiting for the river ice to break up. It has paid out more than $14 million in its history.

Participants buy a $2.50 ticket and try to guess the exact day, hour and minute the ice will go out. In 2017, 42 people correctly guessed the Tanana River’s 2017 breakup time as noon Alaska Standard Time on May 1. By tradition, the Ice Classic uses Alaska Standard Time rather than Alaska Daylight Time.
