LEHIGH TWP., Pa. - Blue Mountain in Lehigh Township is "back burning" on Sunday evening to deprive the fire of fuel.

Officials say that the fire is being drawn to areas that have already burned so that without fuel, it will extinguish.

Janet Steigerwalt is one of the people who looked on at the Blue Mountain brush fire on Sunday.

The DCNR said it has spread to 150 acres in Lehigh Township.

"It's devastating," said Steigerwalt.

Lehigh Township Volunteer Fire Company Assistant Chief Brian Krische said firefighters have slowed the fire from advancing east.

First responders were called to it all just before 2 p.m. on Saturday.

"They have dozer lines in there right now. There's three bulldozers up there and there's two helicopters still making helicopter drops onto the fire to slow the progression," said Brian Krische, Assistant Chief with the Lehigh Township Volunteer Fire Company.

Krische said a controlled burn is underway.

"We're going to start at the low base of the fire where the controlled cuts have been put into place, so the fire doesn't spread to the back of homes, but we're going to burn the mountain up to the burned-out area already to stop any further progression," said Krische.

Meanwhile, donations from the community pour in.

"We put out a post asking for some simple things like water, chap stick, sunscreen, you know just simple things and everything like that," said Krische.

Steigerwalt and Lisa Kishbaugh with T.W. Cooper Insurance dropped off donations.

"Kind of heartwarming that the whole community is coming together, you know it's sad that it takes a tragedy to have that, but it's nice that people step up when needed," said Kishbaugh.

Anything leftover will be donated to a local food bank.

"It's just so overwhelming what the community has done for us," said Krische.

The Assistant Fire Chief said there have not been any evacuations or injuries.

He said there is fire apparatus at each home along the effected area to be safe.

The Assistant Chief said a point of origin for the fire has been identified and DCNR will do its investigation from there.
