A mammal's Breathing Hole

There is an old fence/tree line that runs near the centre and along the length of the woodlot. I call it the Hawthorn line since it is made up mainly of hawthorn trees and basswood trees. Along this line I found a hole in the snow pictured here and the outer rim of the hole was covered in hoar frost crystals as shown in the photo. This is typical of a breathing hole for a mammal that is hibernating or holed up in the snow. There are at least two of these that I know of on the property. The other is from underneath an old barn floor.
