Washington's biggest wildfire is now approximately 50 percent contained, as crews resume work on a fire line on its western perimeter.

The Colockum Tarps Fire has burned across 125 square miles south of Wenatchee. Managers say crews are conducting burnout operations in the steep, forested draws where it's burning, essentially using fire to fight fire by depriving the main blaze of fuel.

It's expected to take another three to four days for crews to finish the remaining three miles of fire
line and contain the fire.

About 750 people were assigned to the fire Saturday.

Firefighters in north-central Washington also are working to contain several small fires sparked by lightning on Thursday.

Near Goldendale, the Mile Marker 28 Fire was 82 percent contained Saturday.
