Quick Answer
Leaving a quinzhee solid provides better structural integrity and insulation, while hollowing out can make it more prone to collapse and reduce its insulating properties, making it a less desirable option for shelter.
Building a Solid Quinzhee
When building a quinzhee, it’s essential to leave the walls and roof solid, at least partially, to maintain its structural integrity. This can be achieved by digging a trench around the quinzhee, about 1-2 feet deep, and leaving a 1-foot wide strip of snow on top. This will help support the structure and prevent it from collapsing under its own weight or external factors like wind.
Hollowing Out a Quinzhee: Risks and Considerations
Hollowing out a quinzhee can be tempting, especially when looking for a place to store gear or build a bed. However, this approach can compromise the structure’s integrity, making it more susceptible to collapse. If you do choose to hollow out a quinzhee, it’s crucial to do so carefully, using a shovel or other tools to avoid damaging the walls or roof. A general rule of thumb is to leave at least 2/3 of the quinzhee solid, with a maximum of 1/3 hollowed out. Be cautious of the weight and size of the snow, as excessive hollowing can cause the structure to become unstable.
Insulation and Maintenance
To maintain the effectiveness of a solid quinzhee, it’s essential to ensure that it’s well-insulated and protected from external factors like wind and moisture. A layer of snow or pine needles can help to insulate the structure, while a tarp or other waterproof material can protect it from precipitation. Regular checking and maintenance, such as patching any holes or cracks, can also help to extend the lifespan of your quinzhee and keep you safe and warm.
