I get chills just reading this thread. I've canceled two hikes in the Northern Presidentials this winter and I actually canceled one along the Franconia Ridge line today because of the extreme cold and wind we are experiencing.
I was kicking myself all day thinking I should have gone. It's such a hassle to organize gear, get partners together and get up there, you hate to have to shut it down. This a chilling reminder that you can never be too careful in those Mountains this time of year.
My thoughts are with her and her family. I can relate to what pushed her up the Mountain, I just wish she made a better choice... I can't imagine breaking tree line in those conditions and pushing forward.
