Roane County crews are working to contain and put out a 20 acre wildfire between Harriman and Oak Ridge.

The fire is in the Clacks Gap area on a hillside near Edwards Road and Sugar Grove Valley Road.

The cause of the blaze has not been determined.

Rainfall approaching the area this morning should aid firefighters in putting it out.

As of the last report early this morning, officials said the fire is 60 percent contained.
