Officials say a wildfire at Lake Wenatchee is 35 percent contained, a day after burning four vacation homes and charring six acres.
U.S. Forest Service spokesman Mick Mueller said the structures were summer homes permitted on Forest Service land, which were adjacent to the Wenatchee Ranger Station.
Mueller said the fire is reported to have been caused by people, but it remains under investigation.
In Southern Oregon, a wildfire near the rural community of Williams on Saturday threatened 150 homes. Seventy-five of them were evacuated on Friday, but residents have been permitted to return.
The Pacifica fire is burning on about 500 acres, or three-quarters of a square mile.
Oregon Forestry Department spokesman Brian Ballou said firefighters are trying to push into the fire on all sides.
Gov. John Kitzhaber authorized additional firefighters and equipment.
