What I Learned:
1. The heavier the snow, the smaller your pile of snow has to be…but the tougher it will be to dig out.
2. If I have to build one north of the tree line, I will do so very slowly. It's easy to work up a sweat when you build a quinzhee and without wood to build a fire that can be a killer.
3. Don't keep piling the snow you dig out on top unless you compensate with thicker walls. I've had one collapse on me in the past.
4. Use a small shovel for digging out the inside. A large shovel will cause all kinds of problems, although it's good for getting it started.
5. Although I didn't dig out the shelter while it was raining, I realized that for a while, it would even work as a rain shelter to keep you dry.
6. Piling up the snow I dig out of the shelter on either side of the door does a good job at keeping the wind out.
