Quick Answer
A quinzhee should be built in a roughly circular shape with a diameter of 8-12 feet for maximum strength and stability.
Quinzhee Geometry
When building a quinzhee, use a mound of snow that’s roughly 8-12 feet in diameter and 4-6 feet high. This diameter and height will allow you to create a stable, symmetrical structure that distributes the weight evenly.
Snow Packing Techniques
To achieve maximum strength, pack the snow in a way that creates a uniform thickness throughout the quinzhee. Start by digging a shallow hole and packing the snow in a series of concentric circles, working your way up. Use a shovel or a snowboard to compact the snow, then use your feet or a board to smooth out the surface. As you add layers, gradually decrease the diameter of each circle to create a more stable structure.
Snow Depth and Structural Integrity
For a quinzhee of this size, aim to create a wall thickness of around 2-3 feet to ensure structural integrity. This thickness will provide sufficient support for the roof and prevent collapse in the event of wind or snowfall. If building in an area with deep snow, you can create multiple layers of quinzees, each with a diameter of 8-12 feet, to create a larger, more stable shelter.
