Watch: Yellowstone grizzly bear charges reckless tourist

A woman watching grizzly bears in Yellowstone National Park this past week was charged by one of the animals as she stood in the open, vulnerable to attack.

A Yellowstone National Park tourist who had been warned that she was dangerously close to grizzly bears was charged by one of the animals in a recent encounter caught on video.

The accompanying footage, captured by Darcie Addington from inside a vehicle and shared with NBC Montana, shows the bear in a bluff-charge behavior intended to clear a perceived threat.

NBC Montana reported that the bear closed well within 30 yards of the woman, who became frightened, turned her back on the animal, and quickly walked to safety.

Addington said several people tried warning the unidentified woman that she was not giving the bears enough space.

Yellowstone regulations state that tourists, who are responsible for their own safety, must remain at least 100 yards from bears and wolves.
