Crews are working ahead of a wildfire burning in Caldwell County as they try to keep it from spreading.
The North Carolina Forest Service is burning out an area ahead of the main fire, hoping to keep the big fire in check.
Eyewitness News could see firefighters using fire to fight the wildfire north of Lenoir. For three days now, 50 firefighters have worked to keep the High Eagle fire from spreading.
On Wednesday, they went on the offensive setting fire to part of the mountainside along a fire line they hope to hold.
"You can put out a fire one of three ways. Take away the oxygen, the fuel, or the heat. So we're taking away the fuel out here by doing this,” said Joe Shoup with the N.C. Forest Service.
Fire investigators are still trying to determine what started the fire located close to Highway 321 about 8 miles north of Lenoir. They said no homes are threatened right now and they want to keep it that way by digging a line around the entire fire.
"You have to drop back to where the terrain will allow you to put in a containment line. There are a lot of rock cliffs in here that are very dangerous," said River Miller with the N.C. Forest Service.
Firefighters expect to be at the scene through Wednesday night. They said by the time they have this fire under control nearly 150 acres will have burned.
