A mountain biker has been attacked and killed by a grizzly bear as he was riding along a trail just outside Glacier National Park in Montana.
Brad Treat and another cyclist were in the Halfmoon Lakes area of the Flathead National Forest on Wednesday when they surprised the bear.
The bear knocked Treat off his bike, and the second rider left to look for help, Flathead County Sheriff Chuck Curry told the Associated Press.
Authorities found the 38-year-old’s body at the scene, but not the bear. Wildlife and law-enforcement officials are searching for the grizzly.
Treat was a law-enforcement officer with the US Forest Service.
"Brad was an integral member of our area law enforcement team and a friend to us all," Curry said.
Treat grew up in nearby Kalispell, where was a standout distance runner in high school, his former coach, Paul Jorgenson, told the Flathead Beacon newspaper.
"He was a really good runner but he was also a kind-hearted person who cared about people," Jorgenson told the Beacon.
The second rider, who was not identified, was not injured.
Authorities have closed the area, which is about 3 miles away from Glacier's west entrance, for public safety.
Grizzlies in the Lower 48 states have been designated a threatened species since the 1970s, but their numbers are increasing and so are conflicts between humans and bears.
The grizzlies in the Glacier area among about 1,000 bears in the Northern Continental Divide Ecosystem, which also includes the Bob Marshall Wilderness south of the park. At least 700 more grizzlies live in and around Yellowstone National Park, which is roughly 360 miles south of Glacier.
Six people have been fatally mauled by bears in the Northern Rockies since 2010, but those deaths were mainly in the Yellowstone area. Glacier officials say there are usually one or two non-lethal encounters between bears and humans each year inside the park.
Before Wednesday, there had been 10 bear-related human deaths in Glacier since the park was created in 1910. The last was in 1998, when three bears killed and partially ate a park vendor employee while he was hiking.
In the most well-known Glacier attacks, bears killed two people in different parts of the park in a single night in 1967. Those attacks became the subject of a 1969 book by Jack Olsen titled "Night of the Grizzlies," and later a documentary by the same name.
