Fire crews are resting Sunday night, bracing for another day in the George Washington National Forest as they continue battling a brush fire.

The U.S. Forest Service says it got calls about the fire around 5:30 a.m. Sunday and officials were out until dark that night.

So far, it's estimated to be 100 acres in size and growing.

Elwood Burge, an agency administrator for the U.S. Forest Service, says this time of year is the peak fire danger season for those in the forestry field.

"It's just crunch, crunch, crunch, it's really dry, and it definitely will burn right now," says Burge.

He says they've been anticipating fires, so they had actually brought it smoke jumper crews from other states.

However, even with 20 firefighters in the forest Sunday, he says it's a difficult battle.

"Just the nature of the terrain. It was really hard to access this fire, even walking is extremely difficult in that area," says Burge.

He says the area is a beautiful resource and one many people in the Valley take advantage of, so they want to keep everyone safe and the forest preserved.

"One thing we want to do with this fire is manage it to benefit multiple resource objectives. So try to take the fact that we have a fire and use it to our benefit and approach some wildlife habitat," says Burge.

Tom Ledbetter, the fire management officer for this fire, says he hopes the fire is at least contained within a week.

"We've still got the leaves on the trees, and these leaves will be falling another week or two. And as long as they're falling they'll find hot embers on the ground and that'll want to burn, so we'll be out here for probably two to three weeks dealing with this fire," says Ledbetter.

Burge says they have a larger contain area for the fire, and he's pretty confident they can keep it within that range.

Crews are also using existing roads and creating hand lines to help contain the fire.
