Actually they could tunnel in. A tunnelled passage to the interior of an igloo was common to reduce wind or the loss of heat. Yeah, due to the insulative properties of even snow and ice, you could get warm inside an igloo. They were used by the indigenous people (the Inuit) of northern Canada and Alaska as shelter when hunting in winter.
Polar bears of course don’t make igloos but they do dig out little den’s in the snow to keep warm or birth their cubs. Seals do it too but dig their dens into the snow up from the water. The polar bears know this and hunt for these little dens to pop their nose in for a plump little snack. Yeah, sorry, yet again the young in the wild are often food.
And of course there were no igloos in Antarctica as there were no indigenous people of Antarctica. But that would have been cool, those people would have been hardcore.
Here’s a list of stuff I’ve been busy with around here (reprint! 🙂 ).
That’s all for now. See you tomorrow!
