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.

A normal hike turned into a nightmare when a visitor of Montana's Glacier National Park was attacked by a bear. The hiker and his party came up against the bear while near the trailhead of Grinnell Glacier Overlook per a release from the National Park Service.

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.
