Hand-Drawn Stats for Ice Breakup Predictions

About this episode

The episode discusses the historical methods used by scientists to predict ice breakup on the Tanana River for a local contest.

In 1976, scientists at the University of Alaska Fairbanks hand-drew probability maps to predict the Tanana River’s ice breakup for the Nenana Ice Classic—a quirky contest where you bet on the exact melt time. Using decades of data, they smoothed out irregular patterns into a bell curve, all with typewriters and graph paper, before computers even existed. The most likely breakup? May 6th at noon, with a 9.6 in 100,000 chance of winning. Betting on the 1% contour gave you a 1 in 100,000 shot, while the 0.1% line was a 1 in a million gamble. But hey, you didn’t have to play by the map—historical data alone was useful, and some folks even joked about throwing darts at the peak of the “probability hill.” It’s a charming glimpse into how science, stats, and a little humor once teamed up to solve a local ice puzzle.
