SENEY, Mich. (AP) - Officials say a wildfire believed to have been triggered by lightning has expanded to at least 3,200 acres of a wildlife refuge in Michigan's Upper Peninsula.
The U.S. Fish and Wildlife Service says crews are working Thursday to control the fire at Seney National Wildlife Refuge. High winds and dry conditions have hampered firefighting efforts.
The Michigan Department of Natural Resources says the blaze that was estimated at 2,500 acres Wednesday had spread to at least 3,200 acres Thursday.
So far, no injuries or building damage have been reported.
Michigan Highway 28 remains open as aerial control efforts succeed in limiting the spread south of the highway.
The fire started Sunday. The refuge covers 95,000 acres in northern Schoolcraft County, about 85 miles west of Sault Ste. Marie.
