A wildfire in Oregon has burned across 5,000 acres in the Columbia River Gorge, forcing the evacuation of several dozen buildings.

Spokesman David Morman said he had no reports of any homes burning Monday in the Government Flats Complex of fires. However, he says one of two structures that burned Sunday had been used as a residence.

Nobody has been injured in the fire, KPTV.com reported.

Morman said about 55 structures were ordered evacuated Monday, although he could not say how many were homes.

To the west, smoke from a grass fire on an uninhabited island in Columbia between Portland, Ore., and Vancouver, Wash., disrupted Monday evening rush hour traffic on area freeways.
