WEST HARRISON, Ind. --
More than 75 firefighters battled a brush fire Wednesday in Indiana.
Drivers spotted the flames burning around 5:30 a.m. at a campground along Interstate 74 near Saint Leon.
The blaze quickly spread, and firefighters said it burned more than 100 acres of wooded area.
Authorities said the fires center was difficult to locate in thick morning fog, and officials at the nearby park said they feared the fire would damage their facilities.
At the top of the hill we have a 48-room lodge two dorms, a dinning hall and multipurpose building, so obviously we want it to be contained as it appears to be, said Brenda Hail, manager of the conference center.
Firefighters remained on standby throughout Wednesday evening in case the fire rekindled.
You're getting the fire running across dead leaves that are down, but it's still burning underneath, (so if) you get a wind gust and the fire regenerates itself, and that's the problem we're finding out, said Miami Township Fire Chief Jim Hughes.
No injuries were reported, and the cause of the fire remains under investigation.
