Quick Answer
Best Practices for Quinzhee Entrance Design involve creating an entrance tunnel that is wide enough for a person to crawl through, with a slope of about 1:4 to facilitate easy entry and exit, and a width that allows for comfortable movement.
Designing the Entrance Tunnel
When building a quinzhee shelter, the entrance tunnel is a crucial component that affects the overall usability and safety of the shelter. A well-designed entrance tunnel should be about 30-40 inches wide and 24-36 inches high, allowing a person to crawl through comfortably. The tunnel should slope downwards at an angle of about 1:4 to prevent water from accumulating inside the tunnel and to make it easier to exit the shelter in case of an emergency.
Slope and Orientation
The slope of the entrance tunnel is critical to ensure that it remains dry and accessible throughout the year. A slope of 1:4 means that for every 4 inches of horizontal distance, the tunnel should drop 1 inch. This slope also helps to prevent snow from accumulating inside the tunnel and makes it easier to dig out in case of an emergency. Ideally, the entrance tunnel should be oriented towards the direction of prevailing winds to prevent snowdrifts from accumulating outside the shelter.
Reinforcing the Entrance
To make the entrance tunnel more stable and secure, it’s essential to reinforce it with additional snow or branches. You can do this by digging a trench around the entrance tunnel and packing the snow inside to create a solid barrier. Alternatively, you can use branches or poles to create a framework around the entrance tunnel and pack snow around them to reinforce the structure. This will help to prevent the entrance tunnel from collapsing under the weight of snow or ice.
