HELENA, Mont. -- Montana authorities say a grizzly bear attacked and killed a 38-year-old mountain biker riding just outside Glacier National Park.
Flathead County Sheriff Chuck Curry says Brad Treat of West Glacier was killed Wednesday afternoon on a trail in the Halfmoon Lakes area of the Flathead National Forest.
Curry says Treat was biking with another person when they surprised the bear, which knocked Treat off his bike. The second rider left to look for help and was not injured.
Curry says authorities are looking for the bear.
Treat was a law-enforcement officer for the U.S. Forest Service.
The area is about 3 miles from the park entrance at West Glacier.
Before Wednesday, there had been 10 bear-related human deaths in Glacier since the park was created in 1910.
