Quick Answer
Common mistakes when building quinzhees include inadequate snowpack, insufficient wall height, and failure to create a smooth roof slope.
Insufficient Snowpack
Building a quinzhee without sufficient snowpack is a recipe for disaster. A minimum of 12-18 inches of fresh, powdery snow is necessary to provide the structural integrity required for a quinzhee. Attempting to build with less snow will result in a weak and unstable structure. Additionally, the snow should be moist and powdery, not wet or granular, as this will provide better insulation and structural support.
Wall Height and Angle
A quinzhee’s wall height and angle are crucial for its stability and effectiveness. Walls should be built to a height of at least 4-6 feet, with a slope of 30-40 degrees to allow snow to slide off easily and prevent collapse. The walls should also be built with a slight overhang at the bottom to prevent snow from accumulating and weakening the structure.
Roof Slope and Shape
A quinzhee’s roof should be shaped like a dome, with a slope of 20-30 degrees to allow snow to slide off easily. A smooth, rounded roof will also help to distribute the weight of any snow accumulation evenly, preventing collapse. The roof should be built with a slight overhang around the edges to prevent snow from accumulating and weakening the structure.
