Quick Answer
Building a quinzhee too small can provide inadequate protection from the elements, leading to hypothermia or other cold-related illnesses, especially if occupants are exposed for an extended period.
Insufficient Space and Snow Load
Building a quinzhee too small can lead to structural instability, causing the walls to collapse under the weight of additional snow. A standard quinzhee typically requires a snowbank 6-8 feet wide and 8-10 feet long, with a depth of 3-4 feet to provide adequate space for occupants to sit and sleep. Insufficient space can also lead to moisture accumulation, causing the shelter to become damp and uncomfortable.
Reduced Insulation and Cold Transfer
A smaller quinzhee may have reduced insulation, allowing cold air to penetrate and warm air to escape. This can result in a colder interior temperature, making it more difficult for occupants to stay warm. Additionally, the reduced volume of the quinzhee can lead to cold spots, where cold air is trapped and unable to escape, exacerbating the cold transfer issue.
Designing an Effective Quinzhee
To avoid these issues, it’s essential to design a quinzhee with sufficient space and structural integrity. A good rule of thumb is to build a quinzhee with a volume of at least 100-150 cubic feet, using a larger snowbank if possible. This will provide a safe and comfortable space for occupants to shelter from the elements, reducing the risk of cold-related illnesses and other hazards.
