Post resources for surviving the harshest winters imaginable. I've lived most of my life in cold climates, done a few multi-day solo winter camping trips, and worked a bunch of cold jobs but I recently heard about the Navy SEALS Rewarming Drill and it sounds like a good challenge. I'm looking for some books/videos so they I can try to push myself further. Things like constructing snow structures, austere hypothermia/frostbite care, and planning extended trips. I know the Army Rangers have an arctic division but I can't find any of their operational handbooks
