    I think part of the problem is the swinging temperatures as much as the actual cold. There are several different classifications of dzud, and the “iron dzud” in which heavy snowfall melts and then refreezes into a solid layer of ice seems to be what the article is describing. Obviously temperatures anywhere near -50 C are brutally cold regardless, but if everything is covered in a layer of ice then it doesn’t even matter if the animals can keep warm because there’s nothing they can get at to eat.
