 And what I find most interesting in all of this is that the key to building a good igloo is actually the type of snow. Pokangayuk is the firm snow, which is the stuff that's below the soft, powdery new snow. And that's what Inuit cut into blocks and used to build an igloo. I mean, a house made of snow doesn't seem like the warmest thing, but I've never been in an igloo. Am I wrong?
