This tree seems to have an exhalation of frost emerging from a hole at its base.
Looking around the forest, many such holes have frost exhalations. I’m not sure what causes this – I speculate that the holes lead down to the non-frozen moisture underneath, maybe, and with the air as cold as it has been (5ºF at night), these holes exhale their moist air into the the atmosphere and it freezes. Then I wonder, maybe a small animal is living in each of these holes?
