The weather at this incident was cold, cold, cold. Temperature was in the low teens (F) and it did not take too long for everything to freeze up.
The top picture is taken to the road and we will call the road side of the structure Side 1. The middle picture is the 1-2 corner and in the center is what was left of the small overhang that was above the entrance door. to the left and below this overhang is the garage area with what is left of the house in it. There was also a car in that pile.
Picture 3 shows the opening in side 2 where the overhead door was. Note where the snow (about 4" accumulation) was melted from the radiant heat.
