Quick Answer
The best snow types for quinzhee construction are powdery and dry snow, as they can be easily packed and maintain their structure. Avoid wet, heavy, or slushy snow, as it will collapse under its own weight. Optimal snow conditions are typically found in temperatures between -10°C and -5°C (14°F and 23°F).
Ideal Snow Conditions
Quinzhee construction requires snow with a high water content, typically above 10%. Powdery snow, often found in areas with frequent wind, is ideal for building quinzees. This type of snow is lightweight, easy to shovel, and maintains its shape when compacted. If possible, choose a location with snow that has been recently blown by wind, as this will ensure a stable and strong structure.
Building the Quinzhee
To build a quinzhee, start by piling the snow into a large heap, ideally 3-4 meters (10-13 feet) in diameter and 1.5-2.5 meters (5-8 feet) high. Use a long-handled shovel to pack the snow down, starting from the base and working your way up. This will help create a solid foundation and prevent the quinzhee from collapsing. Pack the snow in layers, with each layer slightly smaller than the one below it, to create a stable and even structure.
Tips for Success
When building a quinzhee, it’s essential to work efficiently and pack the snow quickly to avoid it becoming too heavy and collapsing. Aim to complete the quinzhee in under an hour, as this will help maintain its structure. Additionally, ensure the quinzhee is built in a location that is protected from wind and extreme temperatures, as these can cause the structure to collapse or become unstable.
