The man was hiking was with a group when they encountered a bear on the Highline Trail near the Grinnell Glacier Overlook trailhead, according to a news release from the park service.
After the attack, which authorities did not describe, the man, who sustained non-life-threatening injuries, hiked more than a mile in a mountainous area to Granite Park Chalet with the help of park rangers and other hikers, the Park Service said. He was then flown to the southwest edge of the park and taken by ambulance to a hospital in Whitefish, Montana, park officials said.
Glacier National Park rangers closed several miles of the Highline Trail after the attack. Park officials said they did not know whether the bear that attacked the man was a black bear or a grizzly bear.
