Building an Igloo: Four Steps

"Build an Igloo"
Wired How-To Wiki

"If you're planning an excursion into the frozen tundra, learn a few tricks from those who've lived there the longest. The Inuit of Northern Canada have been making temporary shelters out of snow and ice as long as the white stuff has been around...."

There's a four-step procedure that seems to be moderately practical.

In the Lemming's opinion, though, the prudent course of action is to avoid being in a position where one needs to know how to build an igloo.

On the other hand, if you're doing it for fun: Enjoy!
