Will High Winds Compromise the Structure of a Quinzhee?

Quinzhee Structure and Wind Resistance

A quinzhee is a type of snow shelter constructed by piling snow into a large heap and allowing it to settle. The resulting structure is strong and resistant to wind, but its integrity depends on the thickness and quality of the snow. A minimum of 4-6 feet (1.2-1.8 meters) of snow depth is recommended to build a stable quinzhee.

Reinforcing the Quinzhee against High Winds

To make a quinzhee more resistant to high winds, it’s essential to reinforce its structure. This can be achieved by building a snow wall around the quinzhee, at least 3-4 feet (0.9-1.2 meters) high, to protect it from wind-driven snow and debris. Additionally, a thin layer of hard-packed snow or ice can be applied to the roof to prevent wind-driven snow from penetrating and weakening the structure. If winds are extremely high, consider building a windbreak or a snow trench to reduce the pressure on the quinzhee.

Snow Conditions and Wind Resistance

The type of snow used to build a quinzhee also plays a crucial role in its wind resistance. Powder snow is generally more resistant to wind than wet or heavy snow, which can be prone to avalanching or collapse. In areas with high winds, it’s essential to choose a location with a natural windbreak or to build a quinzhee in a wind-protected area.
