NEWBERRY, Mich. (AP) - Officials say a wildfire in Michigan's Upper Peninsula has grown to slightly more than 21,000 acres.
Tahquamenon Falls State Park is closed. The Department of Natural Resources says wind gusts could be 15 mph Saturday. It warns that "extreme fire conditions persist." The fire, known as the Duck Lake Fire, is in Luce County, north of Newberry.
State officials say the fire is 20% contained and describe it as long and narrow, stretching 11 miles north to Lake Superior.
Access has been tricky because there are few roads. Gov. Rick Snyder has sent aircraft from the Michigan National Guard to douse the flames. Air tankers from Minnesota are involved.
More than 40 structures have been threatened and six are lost. It's not clear whether they were homes or outbuildings.
