Drawing from a lifetime of snow experience, two Inuit men in Canada’s Far North find a site full of hard-packed snow for their igloo, or iglu in Inuit. To insulate and protect against wind and cold, a quick, overnight snow shelter can be built by an experienced person in just 40 minutes, or as many as two days might be spent perfecting a longer-term, family-size structure.
The igloo above takes around 90 minutes to build. Cutting out thick snow blocks with large knives, their only tool, the two men construct a compact spiral wall that is shaped to slope upwards, eventually leading to a keystone piece at the very top. Their years of practice makes it look easy.
