Compared to other snow shelters the Quinzhee is less demanding of the snow conditions. You don't need very deep snow (as is required by a Snow cave or Snow trench for example.) or hard packed snow which is required for Igloos.
The snow heap freezing before being dug out
The process of building a Quinzhee looks like this:
- Pile up as much snow as you can in a heap using a shovel
- Compact the heap a bit by pounding it with the shovel
- Let the heap freeze for at least 30 minutes
- Insert 20-30cm sticks evenly into the heap all around the top so that you will not dig through the wall when digging out the living compartment
- Dig out the living compartment and watch carefully so that you don't dig through the wall when you hit the sticks
- Optionally create a door of some kind
Step one is by far the hardest one. It took my about 45 minutes with a big shovel and this was for a heap that would probably only fit me in curled up position. It should help to have several people do the shoveling. It is very important to let the heap freeze properly, otherwise it will collapse. Especially when build out of cold powder snow like this Quinzhee. I let this one freeze for 2 hours.
The biggest reason to build a quinzhee - The fun factor
I have heard that those who have tried sleeping in Quinzhee say that it is quite comfortable and very warm, but also a bit damp. So far I have only built mine just outside the house for fun purposes. It's a great activity for the kids, especially the digging. I must say however that the hard work makes me long for the ICEBOX Igloo Tool.
