A major area of Glacier NP is closed, including much of the CDT through the center of the Park. It's a horror. I've been there hiking for the past week. Camped at Reynolds Creek Sunday night.
Services in the area are widely disrupted because of the evacuation of Rising Sun and St. Mary. Many trails and backcountry campsites are closed.
