woodpile in Finland
Woodstacking method from Finland

Doug Hren writes:
Saw this unique way to stack and ventilate a wood pile on a recent trip to Finland.
(1) Throw it in a contained pile
(2) throw a tarp over the top that slopes away from the center
(3) make a hole in the center of the tarp with a vented roof/chimney structure.

Stack was about 12 feet tall with wooden vent structure.
