Just quartered a log chunk down to a few inches from the bottom, start kindling on the top where the x meets, and tada! It's really cool. Simple but functional as heck. If cut flat, it'd make a good cook surface. Posted via Mobile Device
Swedish log. The top is pulled open and filled with tinder to get it started. Try the army way. Dig two holes about to your elbows and connect them down below. Light the fire in one hole. The other hole allows more air. Apparently it isn't detected at night.
