The Kent Fire Department continued to monitor the smoldering remains of a wood-debris fire at a Covington wood-recycling facility Thursday.
The blaze broke out at about 10:30 p.m. Tuesday at the facility near Highway 18 and Covington-Sawyer Road, according to a Kent Fire Department media release.
Within minutes, flames shot up more than 100 feet and smoke could be seen for miles.
Firefighters from Kent, Maple Valley and King County Fire District 44 responded to the fire.
The wood-debris pile was estimated at 175 feet by 50 feet and was fully engulfed in flames when firefighters arrived.
After applying more than 2,000 gallons of water per minute with little effect, firefighters decided to concentrate the water on unburned portions of the fire to keep it from spreading.
They stayed at the scene to keep the fire from spreading as the wood burned down.
The cause of the fire remains under investigation.
