Cold wheather survival

I am currently involved in a venture crew. So we go camping every now and again....well one trip was a cold wheather survival trip. We camped in about 2 to 3 feet of snow. It was extremely fun and the fact that nobody go hypothermia or frost bite is amazing. One bad thing about the trip was out stoves didnt work so we had to cook everything over and open fire which resulted in a burnt hand. Also we had to make our own shelters out of ..... snow. The process is find a really deep snowy place then dig out out spot then fill it back up with snow and pile a lot of snow on top of it then let the snow settle for an hour the dig a small door and then carve it out. It was a long process but it was warm and nice overall awesome trip.
