Quick Answer
A quinzhee can be modified for emergency situations by incorporating features that improve its insulation, ventilation, and structural integrity.
Modifying a Quinzhee’s Walls
A quinzhee’s walls can be reinforced by piling snow on top, creating a sturdy dome shape, and then adding a layer of smaller snow bales or even pine boughs to insulate and protect from wind and moisture. For added stability, construct a snow trench around the base of the quinzhee, 2-3 feet wide and 1-2 feet deep, to prevent collapse and provide a barrier against wind-driven snow. This modification will also help maintain a dry interior.
Improving Ventilation and Structural Integrity
A quinzhee’s ventilation system can be improved by creating a small snow tunnel or entrance, reducing the likelihood of carbon monoxide buildup and ensuring a steady airflow. A quinzhee’s structural integrity can be enhanced by constructing a snow-packed roof, with a minimum slope of 45 degrees to prevent snow accumulation and structural failure. This will also aid in snowmelt and help maintain a dry quinzhee.
Additional Safety Features
Additional safety features can be incorporated into a quinzhee by adding a windbreak or snow wall on the leeward side, reducing the risk of collapse and providing a stable surface for cooking or other activities. A quinzhee’s snow surface can also be stabilized by adding a layer of pine boughs or other vegetation, improving traction and reducing the risk of slipping or falling. By incorporating these features, a modified quinzhee can provide a safe and reliable shelter in emergency situations.
