PORT ANGELES, Wash. — All backcountry campfires will be banned in Olympic National Park as of Monday because of the high fire danger.

Park Superintendent Karen Gustin says only campfires in established fire pits in “front-country” campgrounds will be allowed.

Park officials say six fires — all started by lightning — are burning in the park. The largest is the 350-acre Constance fire in the Dosewallips River drainage. On Saturday, 10 firefighters were assigned to that blaze, with helicopters dropping water on it.

Fire danger has prompted officials to close the popular Dosewallips trail from the western park boundary to the junction of Gray Wolf Pass and Dose Meadows trails, the Constance Pass trail, and the trail from Dose Forks to Honeymoon Meadows.
