IVOR—Some 40 firefighters battled five to six brush fires for more than three hours Thursday.

No structures were damaged and no one from the five responding fire departments was hurt, said Ivor Fire Chief Carl Garner.

The cause of the 4 p.m. fire on three properties covering 10 to 20 acres on Corinth Road between Appleton and Unity roads appears accidental, Garner said.

Sparks created by a boat trailer may have triggered the fires, he said. A witness reported seeing someone hauling a boat on a trailer, who seemed to be having problems.

“It was setting off sparks,” Garner said.

The Virginia Department of Forestry is investigating the fire.

“We were able to contain it and control it, but it will probably burn until we get some rain,” Garner said. “The stumps, peat moss and roots will burn and smolder.”

A bulldozer was used to create fire lines to keep the fires from spreading.

Firefighters from Sedley, Hunterdale, Windsor and Wakefield assisted the Ivor Volunteer Fire Department. Ivor Rescue also assisted.

“I appreciate all the help from everybody,” Garner said.
