I’m on 35 of 46 for the High Peaks and have to admit, I would not take Marcy on in the winter. I wonder which trail she was on?
This happens pretty regularly on Mt Washington.
Especially in the summer. You start out and its a nice day. Then you get above the tree line and the weather changes in an instant. Then you can not see 30’.
The issue becomes that the Mountain Rescue still goes out to find your dumb A$$. Any time of day.
More people die of hypothermia on Mt Washington than almost any other mountain in the world outside the Himalayas.
