Quick Answer
Building a quinzhee is generally best done at the end of a snowfall, ideally when the snow is still fresh and not too cold to pack. This allows for optimal snow density and structure. A temperature range of 20°F to 30°F (-7°C to -1°C) is suitable for building a quinzhee.
Ideal Snow Conditions
When building a quinzhee, it’s crucial to select snow that is fresh, moist, and has the right consistency. The ideal snow for a quinzhee is powdery, with a density of 0.1 to 0.2 g/cm³. This can be achieved at the end of a snowfall, when the snow is still compact. Avoid building a quinzhee in extremely cold or wet conditions, as this can lead to a weakened structure.
Timing and Temperature
The ideal time to build a quinzhee is during the late afternoon or early evening, when the snow has been falling for a few hours but is still fresh. This allows for optimal snow density and structure. A temperature range of 20°F to 30°F (-7°C to -1°C) is suitable for building a quinzhee, as it enables easy packing and shaping of the snow.
Building the Quinzhee
When building the quinzhee, start by clearing a circular area of about 8 to 10 feet in diameter. Pack the snow down to create a solid base, then add layers of snow, each about 2 to 3 feet deep. Use a shovel or a snow saw to shape the quinzhee into a cone or a dome shape, and pack each layer as you go. This will help create a sturdy and insulated shelter.
