In 1968 there were an estimated 376 Wigwam burners in Oregon, and the Register Guard reported that at one time, there were over 200 in Lane County alone. Of course, now there are far fewer than that. I have been unable to determine how many wigwam burners are still left. In 1982 there were six in Douglas County, so far, I have only been able to verify two (though I’m still looking!). I’ve also been able to locate two in Lane County, including this one in Mapleton, at Davidson Industries.
Wigwam burners were phased out in the 1970s — a combination of stricter air pollution regulations and the realization that the “waste” being burned could be put to valuable use elsewhere (to create particle board, bark dust for landscaping, charcoal briquettes, and wood pellets, for example). In these photos you can easily see the mesh screen that was used to keep sparks and embers from escaping as the wood waste was being burned.
The Mapleton Wigwam burner is located on the south side of Highway 126 just 4 miles west of intersection at Mapleton. I have not been able to find out much information about this wigwam burner but it appears to be appreciated by its owners.
