A quinzee is a type of snow shelter that is constructed by hollowing out a pile of compacted snow. It is built by gathering snow and piling it up in a mound, then allowing it to settle and harden before excavating the interior. The quinzee provides insulation and protection from the elements, making it an effective winter survival shelter. The accessible materials and simple construction process make quinzee a popular choice for winter activities. It is crucial to ensure safety when building a quinzee, especially in potential avalanche slopes. Following safety tips and understanding the structural properties of the snow can help mitigate risks associated with quinzee construction.


Igloos are snow structures known for their insulating properties and structural strength. These unique shelters are built using accessible materials like snow blocks, which are stacked in a circular pattern. The shape of the igloo helps to distribute the weight evenly, making it resistant to collapse. The thick walls of the igloo provide excellent insulation, trapping warm air inside and keeping the cold air outside. The dome-shaped design helps to withstand harsh winter conditions, such as strong winds and heavy snowfall. To ensure ventilation, an air hole can be created in the top of the igloo. When building an igloo, it’s important to consider the structural properties and use insulating materials for maximum comfort and safety.

Pro-tip: When building an igloo, make sure to pack the snow tightly to create strong, solid blocks that will hold their shape better.

Frequently Asked Questions

What is a snow trench and how is it constructed?

A snow trench is an emergency snow shelter that can be quickly constructed in severe weather conditions during snow activities. It involves digging a trench that is six or seven feet long, two feet wide, and three feet deep. Snow blocks are arranged in an A-frame over the trench, beveling the top edges to fit them together. Loose snow can be used to fill any gaps. Steps can be carved out for easier entry and exit.

What precautions should be taken when constructing a snow trench?

When constructing a snow trench, it is important to choose a safe location away from avalanche slopes or other hazards. Additionally, the snow should be work hardened by stomping on it to increase its strength. The shelter should be constructed quickly, within 30 to 40 minutes. It is recommended to cap one end of the trench, leave the other end open, and cover the open end with a pack to allow for ventilation.

What is an insulated tree well and how can it be used as a shelter?

An insulated tree well is a naturally occurring pit under evergreen trees where snow collects on the boughs, creating a gap. By digging down to the bare ground and creating a small wall of snow, wind can be blocked. Insulating materials can be packed into the well for warmth, and rocks warmed by a fire can be added to the bedding. This can serve as a shelter in winter wilderness emergencies, providing protection from the cold weather.

What is a snow cave and how is it constructed?

A snow cave is a shelter that can be constructed in areas with deep snow. It involves digging into a deep, solid snow bank or drift and forming a tunnel. A shelf or platform should be created for sleeping, and a small ventilation hole should be dug in the roof. However, constructing a snow cave can be dangerous due to risks such as low oxygen levels and collapsing ceilings, so caution should be exercised.

Are there any other types of winter survival shelters?

Yes, there are several other types of winter survival shelters. One option is slab shelters, which involve cutting and positioning slabs of solid snow to form a shelter. Another option is drift caves, which are created by digging a trench and covering it with poles, tree boughs, and an insulating layer of snow. Lastly, the igloo is a spiraling shelter design that can be built using snow blocks.

What are the risks of not having a snow shelter in a winter wilderness emergency?

Not having a snow shelter in a winter wilderness emergency can lead to severe consequences. Without shelter, the cold weather can cause hypothermia to set in quickly, and the body’s temperature can drop to fatal levels within a few hours. Building a snow shelter is crucial for protection against wind chill and bodily cooling in order to survive in the frozen winter landscape.
