GRAFTON, Ill. (AP) - Rain and firefighters have managed to douse a wildfire that damaged nearly 1,500 acres in and near Pere Marquette State Park in southwestern Illinois.

Officials still haven’t pinpointed what sparked the fire that burned for nearly four days before being extinguished Sunday. A fire official says it might have burned for days if it hadn’t rained.

There are no reports of injuries or damage to structures.

Some 100 firefighters from area departments battled the blaze, coming from Greene, Jersey, Macoupin, Madison and Pike counties.

The state park has about 8,000 acres near Grafton, about 25 miles north of St. Louis.
