FAIRBANKS - The deadline to buy and enter tickets for the Nenana Ice Classic is fast approaching.
Now in its 94th year, the classic is a springtime tradition in which Alaskans try to guess the precise moment when the ice will go out on the Tanana River at Nenana.
Officials measured the ice Thursday, and it was more than 50 inches thick - a mark reached only six times in the last 22 years. Last year's thickest measurement was 46.75 inches.
The ice typically starts thinning in early to mid-April.
Last year, the ice went out on May 1. Two winning tickets shared a jackpot of $283,723.
The deadline to enter this year's classic is April 5.
