Are Quinzhees Waterproof During Thaws?

Quinzhee Construction and Water Infiltration

The quinzhee’s waterproofness is often a misconception. While the quinzhee’s design can keep rain and snow out during cold conditions, the structure is still vulnerable to water infiltration during thaws. The snowpack surrounding the quinzhee will begin to melt, creating an uneven surface that can cause water to seep into the shelter. The porous nature of snow also means that water can penetrate the quinzhee’s walls.

Snowpack and Melting Rates

When the outside temperature rises, the snowpack surrounding the quinzhee begins to melt at a rate of about 1-2 inches per day, depending on temperature and humidity. This rapid melting can cause water to accumulate around the quinzhee’s base, leading to water infiltration. The rate at which the quinzhee dries out depends on factors such as ventilation and snow quality. A well-built quinzhee with good ventilation can dry out faster, but it will still be susceptible to water infiltration during prolonged thaws.

Improving Quinzhee Waterproofness

To improve the quinzhee’s waterproofness during thaws, it’s essential to design the shelter with a watertight base and walls. This can be achieved by piling snow in a way that creates a solid, impermeable layer. The quinzhee’s entrance should also be designed to direct water away from the shelter. Additionally, using a water-resistant coating or membrane on the quinzhee’s walls can help to reduce water infiltration. However, these measures may not completely eliminate the risk of water infiltration during prolonged thaws.
