Quick Answer
Test the stability of a quinzhee shelter by tugging the roof and walls gently to ensure they are solidly attached to the snow foundation, and then applying a small amount of weight to simulate wind or snow pressure.
Inspect the Snow Foundation
To test the stability of a quinzhee shelter, start by inspecting the snow foundation. This includes the area where the walls meet the ground and the surface beneath the shelter. Ideally, the snow foundation should be at least 18 inches (45 cm) deep and compacted enough to provide a stable base. Use your shovel or a stick to probe the snow and ensure it is not too powdery or loose. If the snow is too powdery, consider re-packing it or digging a deeper foundation.
Test Wall Attachment and Roof Stability
Once the snow foundation is stable, test the attachment of the walls to the roof. Gently tug on the roof to ensure it is securely attached to the walls. Apply a small amount of weight, such as a heavy backpack, to simulate wind or snow pressure. If the roof begins to sag or the walls start to shift, re-attach them using additional snow or make adjustments to the shelter’s design.
Apply Weight and Observe
To truly test the stability of your quinzhee shelter, apply a moderate amount of weight to the roof or walls. This can be done by stacking snow or placing a heavy object on top of the shelter. Observe the shelter’s response to this weight, paying attention to any signs of sagging, shifting, or collapse. If the shelter holds its shape and remains stable, you can be confident in its ability to withstand wind and snow forces.
