But she was there and could see what's around her, she was able to walk down after summiting Madison, no problem. The mistake she made was after that, not at the car.
I was with my friend, climbing madison from the east and we went over the col. In half an hours, all our equipment was frozen, not too wet equipment because we change our shirt before the timber line.
My partner felt in hypothermia. Is skin was waxe and he felt every five or six step. We were close to the timberline and we set the tent and I make diner. After an hours, he stop shivering and was O.K..
We also have the women at Mt Jackson who was trap by the wind. She decide to do pumped jack all night long instead of going back on the ridge. Today, Dman can understand why she did that.
As for "the mistake was done not at the car, but after". I disagree. The mistake was done before she event took place in the car. The mentality of performance, to risk our life to show how good we are, is a good subject to discuss here. What performance can be more important than life? and if there is nothing more important, why should we risk? or where is the limit between safety and performance?
