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.

A section of a trail in Montana’s Glacier National Park was closed Thursday after a hiker was injured by a bear, park officials said.
