No one injured in rural Boulder house fire

No one was injured Saturday evening in a rural Boulder house fire that displaced the homeowners and generated a large mutual aid response from local and nearby agencies.

The cause of the fire, which started in a closet and caused “extensive” damage to the home’s second floor, was still under investigation Monday evening, said Boulder-Bull Mountain volunteer firefighter Steve Carey.

Firefighters were first dispatched to the house on Upper Valley Road near Foothill Road at 6:37 p.m., Carey said. Those first to arrive, including a firefighter that lives nearby, saw flames “licking through the roof” and through a door, he said.
