In real survival situations this ancient method is tried and true, but for the enterprising modern snow-architect there are a few tips and tricks that can turn a quinzhee from a crude temporary shelter into an awesome winter-long snow fort that'slarger, sturdier, better lit, and faster to build.
Step 1: Materials
- Snow, and lots of it!
- shovels, rakes, and hand trowels
- some shish-kebab skewers (or straws, twigs, etc.)
- large plastic trash bags and twisty-ties
- spray bottle of water
- cake pans
- and more water
Step 2: Choose a Location
Step 3: Inflate and Bury the Trash Bags
We've learned over the years that if you inflate trash bags with air, pile them up in the center of your quinzhee, and then bury them with snow, you save yourself a lot of time[*]. When it comes time to hollow your snow mound out, you just pop all the trash bags and 'oila!' your quinzhee is hollow. No need to spend hours chiseling snow out by hand.
- Inflate your trash bags like a balloon (but please be careful putting plastic bags near your face, and maybe don't let children help with this step). Then use a twisty tie to secure the mouth of the bag, followed by a quick knot to be double sure it's airtight. It can take some practice, you'll probably make a few duds before you get quick at it. Our quinzhee took about 25 trash bags.
- Place your trash bags in a pile and begin to bury them in snow. We've found it works best to go layer by layer, otherwise they are liable to shift and move around a lot.
- Once your snow mound is about the size you want it, throw a bit more snow on top and around all the sides, just to make sure the walls are thick enough structurally. Then use the back of a shovel to smooth out the edges, it you're into that sort of thing.
Step 4: Prepare for Excavation
- First you must take straws, or sticks, or shish-kebab skewers, and poke them into your quinzhee mound every couple of feet. The reason for this is: when you are inside hollowing or smoothing out the interior wall of your quinzhee (even with the trash bag method you'll do some hollowing) you'll have a guide to how close you are to the exterior of your walls. When you see a straw poking through the interior wall, you know your wall is 8-12 inches thick, which is perfect. This way you'll avoid making your walls too thin, or worse, punching a whole in the side or roof of your hut.
- Secondly, spray the exterior of your quinzhee with water from a spray bottle, to help it freeze and consolidate more quickly. This step isn't strictly necessary, but it can't hurt.
Step 5: Hollow Out Your Quinzhee
Just cut a doorway, and begin pulling out trash bags (or if you skipped the trash bags, prepare to move a lot of snow!). You'll want to do a bit of interior smoothing in any case because the trash bags don't create a perfectly shaped interior cavity. This is when you want to switch to hand trowels, rather than full blown shovels. Remember to use the straws or sticks as your guides to wall thickness.
note on size and safety: This is not our largest quinzhee ever built using this method. A few years back we made a 6 foot tall quinzhee shaped like a turtle, with four feet, a tail, and a head for the entrance. It was awesome, and so large you could almost stand up in it; it could fit 4 adults laying down. Sadly it collapsed with everyone inside because we got a bit overzealous with creating windows and side pockets in the walls, ruining the structural integrity of the dome. This brings me to the topic of safety. Never build a quinzhee alone, and never build one so large that the weight of the snow above you could crush or immobilize you if it collapsed. Snow can be incredibly heavy, especially when wet, and you could easily suffocate if you became buried. The Wikipedia page on Quinzhees recommends always digging them out while on your knees, so that if it ever collapses you will have an air pocket beneath your chest and lungs. Sorry to add a serious note to the generally fun topic of snow forts, but safety is key after all :)
Step 6: Adding Ice Windows!
First fill your cake pans with twice boiled water (for crystal clear ice) or tap water (for expediency's sake) and set them outside to freeze overnight. Our temperature was hovering around 31 degrees, so I just set them in the freezer instead.
Once frozen, run them under cool tap water until they are free from the pans, and now your windows are ready to install. Just cut a few window holes in your quinzhee and pack them in (but be careful to not ruin the structural integrity of your dome!)
If you have the time, crystal clear ice windows are the coolest, and really make your quinzhee shine. We just used cloudy normal ice, but as you can see from the photos even cloudy windows are surprisingly great at lighting up the interior space. I guess ours are more 'sunroof' than 'window'.
Step 7: Final and Most Important Step!
After all that time in the snow, enjoy a delicious mug of hot cocoa. You deserve it!
