David took this picture from the doorway, looking up at me and Sage inside the igloo just after we completed it. The top of the door is even with the floor of the igloo in order to trap warm air inside. A trench cut in the center of the igloo makes it easier to get in and out the doorway, and also enables me to stand in the igloo with a couple inches clearance over my head.
