Quick Answer
You can build a quinzhee on unstable snow, but it's crucial to take extra precautions to ensure the structure's stability and your safety. A quinzhee built on unstable snow will require more frequent inspections and potential repairs. This may involve additional resources or time.
Assessing the Site
When considering building a quinzhee on unstable snow, start by evaluating the site’s conditions. Look for any signs of recent avalanche activity or areas with steep slopes. If you notice loose, powdery snow or signs of recent sliding, it’s best to choose a different location. A safe site should have a relatively flat surface and a stable base.
Building the Quinzhee
To build a quinzhee on unstable snow, begin by creating a larger, more stable foundation than usual. This can be achieved by constructing a snow wall around the perimeter of your quinzhee site, about 3-4 times the desired size of the quinzhee. Fill the interior with snow, then pack it down from the outside, starting at the bottom and working your way up. This technique helps distribute the weight more evenly.
Maintenance and Inspections
Given the unstable nature of the snow, it’s essential to maintain a closer eye on the quinzhee’s stability. Regularly inspect the structure for any signs of slumping or shifting. If you notice any issues, address them promptly by reinforcing the structure with additional packing or reshaping the walls as needed. Remember to also monitor weather forecasts, as high winds or heavy snowfall can impact the stability of your quinzhee.
