While living in my cabin in Idaho at 3500’ or so elevation, during the real cold stretches, -20 and below, you’d hear trees cracking with the cold, almost like gunshots.

Same here. About three years ago we had a cold freeze, and I heard several very loud cracks late in the evening.

When I got up the next day several large branches had cracked and were lying on the ground.
