Wigwam burners were popular in the middle of the last century as a way for the timber industry to dispose of waste wood. They replaced open-pit fires which were obvious fire hazards. Then in the mid-1970s they were phased out of use. Many were torn down; others have come down more naturally. Some people, like myself, enjoy seeing the few remaining ones still left in Oregon — icons of a different era.
Therefore, it was with delight that we stumbled across the Oakland wigwam burner last fall. Located just half a mile from downtown Oakland on Stearns Road (look to the south) it is clearly visible from the road.
[Update: Note that this wigwam burner is no longer standing.]
