Alright, there's no gore, but this is absolutely terrifying!

This ain't no position I'd ever want to be in!

When the camera comes on, this guy is already walking backwards at a pretty decent pace. You can see the momma grizzly bear and her two cubs walking toward him.

Momma bear never looks aggressive, or protective, which is a good thing. However, at one point, when you can clearly tell the guy is getting winded, the cubs start running faster toward him.

That's where it gets intense. It's known that grizzly bears, or bears in general, are extremely protective of their offspring. So, the last thing you want is for the cubs to WANT to come closer to you. That's when momma gets pissed.

Watch until at least 1 minute in.
