GRAYLING, Mich. - Crews are battling two forest fires in dry, windy northern Michigan, both of which have forced some people to leave their homes.

The state Department of Natural Resources and Environment says one fire has burned about 5,000 acres in Crawford County's South Branch Township, near the Oscoda County line. Ten structures have been destroyed.

More than 15 residences were evacuated. A Red Cross shelter was being opened at Resurrection Life Center in Grayling.

DNRE spokeswoman Mary Detloff says the fire is mostly on federal land.

The second fire is in Kalkaska County, within the Camp Grayling National Guard base.

Detloff says 10 to 15 houses have been evacuated there. Military personnel are helping DNRE crews fight the 1,100-acre fire.
