Quick Answer
Yes, a quinzhee is a snow shelter that requires reinforcement for heavy snow loads to ensure stability and prevent collapse.
Assessing Quinzhee Stability
A quinzhee’s stability is directly related to its shape and the surrounding snow conditions. Heavy snowfall can weigh down the structure, causing it to collapse. Check the quinzhee’s walls and roof for signs of instability, such as sagging or cracking. If the walls are too steep, they may collapse under heavy snow. A recommended slope for quinzhee walls is between 30° to 45°.
Reinforcing the Quinzhee
To reinforce the quinzhee, add additional snow to the roof and walls to reinforce the structure. This can be done by packing the snow on top of the quinzhee and using a snow shovel to shape it into a dome or a curved shape. The added snow should be packed tightly to prevent settling and collapse. For heavy snow conditions, consider building a snow wall around the quinzhee to prevent drifting snow from accumulating on the roof.
Additional Safety Measures
When building a quinzhee in heavy snow conditions, it’s essential to consider other safety measures, such as building a snow trench around the shelter to provide additional support and protection from wind-driven snow. Ensure the entrance is stable and secure to prevent collapse and ensure easy access. Regularly check the quinzhee’s stability and make any necessary repairs to prevent collapse.
