Quick Answer
To maintain a quinzhee during thaw, regularly inspect and reinforce the structure, and use a mixture of snow and ice to repair any damage. This will help prevent collapse and keep the shelter stable.
Reinforcing the Structure
During a thaw, regularly inspect your quinzhee for signs of weakening, such as cracks, sagging, or water seepage. Check the structure every 2-3 hours, especially during periods of rapid temperature change. Use a shovel or a sturdy stick to reinforce any weak areas, adding additional snow or ice as needed. Aim to reinforce the structure at least 6 inches from the top to prevent collapse.
Repairing Damage
If you notice any damage to your quinzhee, use the following technique to repair it: gather a mixture of snow and ice, and pack it into the damaged area using a shovel or a stick. Aim to pack the mixture in at least 6-8 inches thick to provide adequate support. For larger repairs, consider using a combination of snow and ice blocks, arranged in a staggered pattern for added stability.
Snow and Ice Mixture Ratios
When creating a mixture of snow and ice for repairs, aim for a ratio of 3 parts snow to 1 part ice. This will provide the necessary strength and stability to support the structure. If you’re unable to find ice, you can also use a mixture of packed snow and water, but be sure to let the mixture freeze before applying it to the structure.
