Overnight the temperature dropped to -30 degrees F according to the thermometer outside the back door. I had to stand on tip toes in the doorway to make out the temperature over the drift. I passed the next two days digging up out from the door, excavating the snowmobile, and breaking a snowmobile trail out to the road—all harder than it sounds. There is a lot more winter to come and I am seriously concerned that it will be necessary to put a ladder in the snow hole so as to get in and out of the door.
