A Big Fork, Montana, man shot some frightening video of some hikers in Glacier National Park running from a grizzly bear. The encounter took place on Sunday afternoon, according to Dulé Krivdich, who shot the video, near Hidden Lake.

Dulé described the encounter and what he shot on his Facebook page:

Be Bear Aware Folks.
This was this afternoon hiking back up after visiting Hidden Lake. Just a switchback below where my wife and I just motored through this big fella (I’d say a 500+ pound Grizzly came through a treeline, down a meadow and swiftly on to the trail itself to get to wherever he wanted to go. Now hikers just below on the same trail are totally unaware of what’s heading their way as we from above start yelling that there is a bear barreling down the same trail.
As one yells back “what do we do?”
“Just start making a lot of noise!!! Don’t run!!!! But just then, the grizz made a bluff charge and we saw people booking it like we’ve never ever seen before in our lives. Even in the Olympics. But I think that it was a case of the Bear not knowing people were coming up as the people had no idea but even once they did they still did the worse thing.......they RAN!!! Thank goodness that it all went well afterwards. Other than that it was a beautiful day for a hike down to Hidden Lake.

The Montana Department of Fish, Wildlife, and Parks does not recommend running from bears. On their website, they state: "Do not run from a bear. Running may trigger a natural predator-prey attack response, and a grizzly can easily outrun the world's fastest human."

That's probably easier said than done when you see a grizzly bearing down on you. Thankfully, the hikers all got away safely and lived to tell about their encounter. Meanwhile, Dulé Krivdich has gone viral by being in the right place at the right time.
