Wisconsin wildfire cause investigated

MADISON, Wis. (AP) — Department of Natural Resources officials say there could be air quality problems downwind of the wildfire. The DNR issued an Air Quality Special Notice yesterday. The blaze has destroyed nearly 50 structures and forced dozens from their homes. Firefighters had stopped most of the fire from spreading as of yesterday afternoon.

Residents and owners of vacation properties potentially affected by the northwestern Wisconsin wildfire now have a hotline to call to check on their properties. The wildfire that started Tuesday afternoon has consumed about 8,700 acres in Douglas and Bayfield County. The number is 715-376-4185.

The fire started in an area where workers were doing logging operations. Department of Natural Resources spokesman Ed Culhane says officials are investigating whether a spark from a piece of logging equipment started the fire around 2:30 p.m. Tuesday in Douglas County. No injuries have been reported.
