Which of these is a Canadian snow shelter made from a large pile of loose snow?

I'm Canadian. Never heard of it.

As Boy Scouts we learned to build them to earn our winter survival badge. Pile the snow and pack it down, then press 20cm sticks in the top. Start digging snow from underside until you touch the end of the sticks, this gives you the roof thickness.

WingManDan1, Never heard of it either. But I am an Australian.

WingManDan1, I am also Canadian and have never heard of it. Maybe 'snow fort'?

I truly wish question setters wouldn't just lift chunks from Wikipedia.

So, a kind of casual igloo...
