CANYONVILLE, Ore. (AP) – The Oregon Department of Forestry says firefighters have gotten the upper hand on a wildfire that charred over 13,000 acres (5,200 hectares) and is now 65% contained.

The department said Tuesday that after intensive efforts to combat the blaze, caused by an illegal, abandoned campfire on July 24, firefighters are now securing lines around the fire, felling hazardous trees and mopping up to prevent any further spread.

The Milepost 97 Fire burned alongside Interstate 5 in southern Oregon near the town of Canyonville. No structures were damaged.

Almost 1,200 people were involved in fighting the first large fire of Oregon’s young fire season.
