AP: Smoke from Canadian fires seen across parts of UP
Police say a layer of smoke covering parts of Michigan's central and western Upper Peninsula is from forest fires burning in Ontario, Canada.
Michigan State Police say Tuesday that people in the area have been calling in reports to public safety officials with concerns about the smoke.
Planes flying for the Michigan Department of Natural Resources have been checking for smoke, and pilots report it's blowing across Lake Superior.
Police say there are no reports of fires in the Upper Peninsula.
