The measurement of the ice at a predetermined spot on the Red River came in at 13.013 inches, concluding a contest held this winter by the Empire Arts Center in Grand Forks.
The contest – the Empire's Ice Thickness Challenge – was a fundraiser for the downtown nonprofit theater. It raised more than $1,140 for the Empire, with another $1,140 going to the winners of the contest, who paid a fee to guess the final ice thickness. Since the ice measured less than 15 inches – the lowest that entrants could guess – 15 people who guessed the minimum will split the $1,140 prize money.
Employees of the event sponsor, the AE2S company, drilled a hole and measured the ice thickness at noon Friday, near the obelisk downtown.
