Making an upside down fire. The upside down fire technique rocks. It’s a cleaner burn with far less smoke and better combustion, gives off more heat, needs less tending and uses the embodied energy in wood more efficiently than the tipi-esque fire method.
This is a nicely done three sided shelter. I would have looked for a spot near a rock formation about as tall as the platform. A fire could be built on the rocks and the heat reflected into the shelter. My Hut by CitizenOlek on deviantART
