During long Arctic winters, the Inuit build igloos that are sturdy, easy to construct (for the practised hand) and elegantly simple. Released in 1949, this short documentary from the National Film Board of Canada chronicles the process of crafting an igloo from start to finish, as two Inuit men race against the setting sun to secure shelter on a short winter day.
