Crews from four agencies responded to a fully engulfed fire in an abandoned home on the 13000 block of U.S. 101 in Smith River late Thursday evening.

The building was believed to have been empty at the time of the fire, said Ron Simpson, a captain with the Smith River Volunteer Fire Department and a battalion chief for the Fort Dick Volunteer Fire Department. Simpson said the fire appeared to have started in the northwest corner of the building, but both the origin and the cause of the fire are still under investigation. Fire crews were dispatched at about 11:16 p.m., he said.

It took firefighters from Smith River and Fort Dick fires and CalFire about seven minutes to get the upper hand on the blaze, Simpson said. The Harbor Volunteer Fire Department also provided a water tender. About 45 minutes after the blaze started, Simpson said he was waiting on Pacific Power to shut off the electricity before crews tackled the flames at the rear of the house.

Southbound U.S. 101 between Indian Road and Mouth of Smith River Road were closed while crews battled the fire. Traffic was diverted onto Ocean View Drive.
