I will choose this option. I'm letting my body recover from the arbitrary Avalanche that I suffered. I want to conserve all my energy and rest my numb state of shock body. I don't want to overthink, assuming there's no more further episode of Avalanche. A temporary shelter that's what I need. I 'll look for route 12 in the morning , climbing the snowy mountain at night is not a good idea although I am really dying to find route 12 and find my room mate. I've got to have patience! I don't want to use the only flare gun I've got. Not right now,it might trigger another Avalanche.
