Wood burners, also known as wigwam burners due to their conical shape, were once common at sawmills throughout the Pacific Northwest, where they were used to incinerate the enormous excess of sawdust and scraps that was a byproduct of every mill. As a result of the passage of environmental legislation in the 1970s that outlawed their use, these structures are vanishing from the American Landscape. Through photographs, drawings and maps, this volume examines the history and typology of this little-known vernacular architecture.
