My daughter and I slept in a quinzhee years ago when
she was only 12. The temperature that night was -22 F.!! But we were very warm in that shelter on our two sleeping platforms. And it was very quiet inside. No wind or creaking tree noises at all.

You'll love a Quinzhee. Get "Allen and Mike's Really Cool Backcountry Ski Book"for a LOT of winter camping info and shelter building tips. Only about 25% of the book is on skiing.
