Cold Snap

On Feb. 3, 1947, the Yukon’s Snag airport recorded a temperature of minus 81.4 degrees. One worker reported:

Becoming lost was of no concern. As an observer walked along the runway each breath remained as a tiny motionless mist behind him at head level. These patches of human breath fog remained in the still air for three or four minutes before fading away. One observer even found such a trail still marking his path when he returned along the same path 15 minutes later.

And: “We threw a dish of water high into the air, just to see what would happen. Before it hit the ground, it made a hissing noise, froze, and fell as tiny round pellets of ice the size of wheat kernels.”
