The book Minus 148 Degrees is written about a winter climb of Denali in which a rapid weather change forced the climbers to seek refuge in an emergency snow cave.
The title is a reference to the claim that the wind-chill temperature was negative 148 degrees F.
What was the actual temperature (as opposed to the wind-chill temperature) during this event?
I do not own a copy of the book and cannot find the answer to this, but I assume someone somewhere must know. If we at least have wind estimates we could work backward to estimate the temperature.
I did find an interview with the author of the book in which the interviewer mentions something about negative 40 degrees, but the author neither confirms nor denies this, and it could well be a typo in which 140 was intended, which might be likely as -148 degree wind chill from -40 degrees appears to require nearly hurricane wind speed.
