The fire that burned about 110 acres east of Woodland this week may have been human-caused, officials say.
Cowlitz County Sheriff's Office and state Department of Natural Resources investigators are seeking tips about the cause of the Colvin Creek fire, including names of people who were in the area last Saturday or Sunday.
Information can be sent to the sheriff's office at 577-3092 or Cowlitz Crime Stoppers at 577-1206.
There is also the TIP411 app for smartphones or the option of texting a tip to 847411, with a message beginning with CCSOTip.
The fire above Colvin Creek started early Sunday morning on steep state-owned forest. It has required a large response from firefighters called in from across the country.
By Friday morning, the fire was 80 percent contained and was expected to be completely contained by 6 p.m., said Chuck Turley, the public information officer for the state firefighter camp at Castle Rock Elementary School. Containment involves cutting a line, like a narrow trail, to keep a fire from spreading through brush and groundcover.
The team of firefighters will turn the fire over to a smaller type 2 organization Saturday, and the camp will be taken down, he said. A new camp will be setup at the middle school in Woodland to accommodate the smaller team.
No injuries or damage to private property has been reported.
