Bitterroot National Forest spokesman Tod McKay said the missing firefighter was found at about 3 p.m. walking down a logging road. Fire officials said the man became separated from his crew on Sunday, and spent the night in the woods. When found, the firefighter said he was very hungry. He was taken to a nearby hospital to be checked out, but appeared to be uninjured. 

Update: Wildfire Today is reporting that the firefighter has been found and is uninjured.

A firefighter was separated from his crew while investigating the remains of the Weasel Fire in the Skalkaho area on Sunday.

Curtis Burleigh, president of Ravalli County Search and Rescue says that the man went missing at around 11:00 a.m. Sunday morning and was still missing by 2:00 p.m. Monday afternoon. The missing man is believed to have his wilderness firefighting gear, which should provide him with the basic necessities while lost.

Search and rescue crews started searching on Sunday evening around 9:20 p.m. and were still looking on Monday afternoon.

"All they know is that while they were walking in, he had to stop and adjust his boots," Burleigh said. "He told them that he would catch up to them, but that was the last they saw of him."

Burleigh said the Weasel Fire was already out and that the firefighters were going back in to mop up and make sure nothing new could start up.
