How to Build an Igloo Canadian Igoo br Douglas Wilkinson br 1949 | 10 min br This classic short film shows how to make an igloo using only snow and a knife. Two Inuit men in Canada’s Far North choose the site, cut and place snow blocks and create an entrance--a shelter completed in one-and-a-half hours. The commentary explains that the interior warmth and the wind outside cement the snow blocks firmly together.
