There will be other, more experienced folks jumping in on this thread soon, buit two thoughts jumped into my mind as soon as I read your post.<br><br>1. Make sure you leave details of you plans with someone, including your ETA. I think a key to survivial under the conditions you described will be to make sure someone is going to come looking for you when you need them. <br><br>2. You must make sure you have signaling equipment with you for when the search teams do come looking. A signal mirror is a must. You may also consider a small flare gun. <br><br>Odd, at first blush, an emergency situation in your extreem environment sounds a lot like being adrift in the ocean. Plants for food and fuel are not available. Actually, very little natural resources are available for scrounging. You are almost totally relient on what you carry for survivial, with the exception of water, which is plentiful during warm months. I would guess that there's plenty of water in snow and ice during the cold months, but that would require fuel to melt. So water may be an issue during that time of year.<br><br>BTW, Depending on finances and travel conditions (you didn;t mention if you're camping, hiking, flying. driving, etc.), The link to Dr Keith Conover's site Beachdoc recently provided, had a report on a portable heating device fueled by charcol blocks, HeatPac Charcoal Vest. This may be an item to consider for your car or plane.
