Crews are battling wildfires that have burned hundreds of acres in two sparsely populated areas of north-central Michigan.

Officials with the Michigan Department of Natural Resources said Thursday there are no reports of injuries or deaths in the blazes ravaging the state's Upper Peninsula.

DNR spokesman Les Homan says about 777 acres have burned in Marquette County southwest of Ishpeming.

An estimated 500 people have been evacuated, and the fire is 65 percent contained.

A separate fire east of L'Anse in Baraga County has scorched roughly 480 acres.

The DNR says the fire was about 80 percent contained by noon Thursday. One structure was reported destroyed, and some residents have been evacuated.
