Inside the ice/snow shelter that we built to spend the night at 20.000 ft after a 7 hours climb and after deciding to stay there because of the storm and the risk of going down with no visibility of the end of the rappel that we had to set up. It was a Cold and long night, with the last drops of water in our camelbak, and a small piece of sandwich that I had left as a backup, just in case =)
