Building an Igloo

The igloo is a snowhouse that was used by the Inuit as a temporary shelter on extended winter hunting trips, but not as a permanent home. An igloo can be built in about twenty to thirty minutes - depending on the quality of the snow and the skill of the builder. Click for more information.

Blocks of snow are cut from snow banks using a snow knife and are arranged in the shape of a dome - not row upon row, but rather in a single spiral. Joints are filled in with snow and a hole is cut for ventilation.

The best snow comes from a snowbank formed by a single snowstorm. Blocks taken from snowbanks formed over a series of storms tended to break easily because of the layers within the snow.

Snow is a good insulator. 10 inches / 25 cm of fresh uncompacted snow can insulate about as well as a 6 inch / 15 cm layer of fiberglass insulation, making it a very good material for building a shelter.
