Yea, I've seen the film a few times and read the book a few times ;-)
The storm in the movie was similar to what we went through on Aconcagua. Was impossible to leave the tents except when what I think was the eye passed over and I got this pic. I've never before experience weather like that, it was scary.
Oh wow, sounds scary indeed. Those pictures really stuck with me!
Luckily you made it up and down safely!
