A Yellowstone National Park visitor captured the tense moments after a child got too close to a bison near a boardwalk.

As we saw in a video on Storyful, a group of people including kids were filmed walking on a boardwalk at Yellowstone when a nearby bison appears to charge at one of the children, who runs away.

The footage was the first to ever capture a wolverine in Yellowstone, though biologists know the animals regularly pass through the park.
