(Portland, OR) -- At least nine Oregon State Parks in the valley and along the North Coast are closed or partially closed, due to ice, snow and downed trees. That includes the Bald Peak State Scenic Viewpoint in Yamhill County and the Buxton Trailhead in Washington County. Several restrooms have also closed, mostly in the Columbia Gorge. Visitors are encouraged to check park pages on the state park website before visiting, as well as local forecasts and TripCheck for road conditions, before heading out.
