WEST GLACIER, Mont. -

The National Park Service rangers are searching for a bear wounded in an encounter with a hiker in Glacier National Park.
    
The agency says the encounter occurred Saturday morning on the Mt. Brown Lookout Trail on the west side of the park in Montana.
    
A 57-year old hiker from Texas says he was hiking alone when a bear charged him from an area below the trail.
    
The hiker deployed his bear spray and then discharged one round of his handgun. The bear ran away.
    
The hiker, whose name was not released, wasn't hurt.
    
It's not known whether a grizzly or black bear was involved, but park rangers found evidence that the bear was wounded.
    
The trail has been closed until further notice while rangers search for the bear.
