Quick Answer
A snow shelter provides protection from harsh winds, extreme cold, and precipitation in frosty climates, allowing for a more restful sleep and better survival chances. It can also serve as a makeshift hunting blind for animals like caribou, which often follow established travel routes through snowy terrain. In addition, a snow shelter can be used to store gear and supplies.
Building a Snow Shelter
When building a snow shelter, it’s essential to choose a location with a natural windbreak, such as a group of trees or a ridgeline. This will help to protect the shelter from harsh winds and reduce the amount of snow that needs to be cleared. A good location should also be near a source of water, such as a stream or a patch of lichen, which can be used for drinking and signaling for help.
Shelter Design and Construction
A simple snow shelter can be built using a trench and a quinzhee technique. Dig a trench about 6-8 feet long and 2-3 feet deep, then pile the snow on top of it, creating a wall about 6 inches thick. Pack the snow down with a shovel or a snow saw, then add more layers, repeating the process until the shelter is sturdy enough to support a roof. A quinzhee shelter can be built by piling snow into a large pile, then hollowing it out from the inside.
Food and Water in the Snow Shelter
While building a snow shelter, it’s essential to keep in mind the location of nearby edible plants, such as lichen and berries. These can be used for food and energy, but be sure to identify them correctly to avoid ingesting toxic species. For water, focus on finding a source of fresh snow or ice, or use a water filter or purification tablets to make snowmelt safe to drink. In extreme circumstances, caribou can be hunted using a makeshift hunting blind built into the snow shelter.
