In winter elks move between their shelters and feeding grounds, and they try to keep these paths as short as possible. But some motion is necessary, food is needed as well as keeping watch. Sometimes the elk rests on the snow. The colder the weather, the less they move. So, because of this, it is not worth to go looking for elks during hard frosts: this would be a great disservice to the elk, because he would rush away in terror, and lose valuable energy without purpose.
