Rangers and other hikers helped the man walk more than a mile in a mountainous area so that he could be taken to a hospital, the National Park Service said.

The man hiked over a mile to Granite Park Chalet with assistance and was flown by a "Two Bear Air" rescue helicopter to a spot where he could be taken by ambulance to a hospital in Whitefish. The trail from Haystack Butte to the Granite Park Chalet will remain closed until further notice, officials said.

The National Park Service said it does not know what species the bear belongs to yet, but there are black and grizzly bears in Glacier National Park.
