NW Washington wildfire closes part of highway
MOUNT VERNON, Wash. (AP) -- A portion of a Washington state highway was closed temporarily as fire crews fought a small wildfire burning east of Mount Vernon.
The Skagit Valley Herald (http://is.gd/nEQzqK ) reported that no homes were threatened Thursday and cool, damp weather was assisting firefighters.
The Big Rock fire is named for a 500-foot-high local landmark, which is popular spot for hiking and mountain bikers, although it is not technically open to the public.
The Washington Department of Natural Resources says the two-acre fire was burning in trees on rocky, steep terrain.
Fire officials have not determined the cause but suspect it might have started with a campfire.
To facilitate firefighting, Highway 9 was closed at times on Thursday. A helicopter dropped water on the hillside.
