Firefighters expect to quickly contain a wildfire that broke out before dawn on a logging operation on county forest land south of Hood River.

Rod Nichols of the Oregon Department of Forestry said Wednesday that crews have a bulldozer line along the east flank of the fire, which stood at about 50 acres, and expect ultimately to hold it at about 200 acres.

The fire was reported at 3:45 a.m. within an active logging operation on Hood River County Forestry lands about 10 miles south of Hood River.

It spread rapidly through Douglas fir and ponderosa pine in the early going, but then moderated. Winds up to 30 mph are expected later in the day.

Nichols says no homes or buildings are threatened. The cause remains under investigation.
