I'm a snowmobiler and have a good kit on board all the time. I am generally well prepared, but lack info on building a snow cave, dimensions for a 1 man, 2man, or 3man. How and where to put the cold well, how much ventilation and where? Do I burn a candle, and if so more ventilation? What kind of temps would be considered normal inside a snow cave relative to outside?

And any info gained from experience would be a great help as well. Thanks in advance for all of your input. Love this sight!
