Firefighters in the last three days fueled a twofold growth of what is, in effect, an unintended and unscheduled prescribed burn in Doe Canyon, according to the U.S. Forest Service.

“This is a naturally caused fire, which we are managing; we have decided to allow the fire to move across the landscape, but we are assisting it,” said Andy Lyon, a spokesman working with the Forest Service on the Doe Canyon Fire. “It’s growing primarily because we are adding fire.”
