snöhyddor

Snöhyddor, meaning "snow huts" in Swedish, refers to temporary shelters built from snow, primarily for survival or recreational purposes in cold, snowy environments. These structures are most commonly associated with winter camping, mountaineering, and survival training. The most well-known type of snöhydda is the igloo, a dome-shaped structure traditionally built by Inuit peoples. However, the term snöhydda can also encompass other snow-based shelters like snow caves and quinzhees.

The construction of a snöhydda relies on the insulating properties of snow. Compacted snow, especially wind-packed snow, can trap air, creating an effective barrier against extreme cold. A well-built snöhydda can maintain a temperature significantly warmer than the outside air, often just below freezing, making it a viable shelter against hypothermia. Ventilation is a crucial aspect of snöhydda construction to prevent the buildup of carbon dioxide and to allow moisture to escape.

Building a snöhydda requires specific knowledge and techniques. Igloos, for instance, are constructed from cut blocks of snow that are carefully stacked and interlocked. Snow caves are dug into existing snowdrifts, while quinzhees are made by piling snow and then hollowing out the interior. The effectiveness and safety of a snöhydda depend on the quality of the snow, the construction method, and proper ventilation. While often used for survival, snöhyddor are also a part of outdoor recreational activities and educational programs focused on winter preparedness and wilderness skills.
