PANGUITCH, Utah — It may seem like a small part of a lumber mill went down in flames overnight Wednesday, but that fire is burning into the heart of a Southern Utah town. Investigators still don’t know why a fire broke out in the machinery that cuts logs into lumber at K & D Forest Products, one of the larger lumber mills in the state. Panguitch’s fire chief said the state fire marshall will investigate further. “It’s a pretty devastating fire,” said Dave Dodds, chief of the Panguitch Fire Department. “This is the sawmill part where they take the logs in and square it up and start making boards and stuff. So that kinda shuts down the whole operation.” Fire departments from Panguitch Lake, Bryce Canyon City, Tropic and Henrieville eventually responded.
