And I've gotta' say that the guy really gets around ... he's pretty much a globetrotter.

I am surprised by the overall lack of coverage about this story in the media.

What puzzles me is - if these sounds are a known phenomenon near the Arctic Circle, then why hasn't someone provided more info. Surely the Intuit people must have a name and a tradition for this sort of thing. And if these sounds are abnormal ... why are they happening now??
