New video shows a man approaching a pack of wolves in Yellowstone National Park. Keith Allen Kerbs recorded the footage on October 6, saying he was photographing the five black wolves when the man approached them.⁣ ⁣ The video shows the man spraying what he describes as bear spray at the wolves as he enters a ravine. The wolves eventually backed off, and the man walked away. ⁣ ⁣ The National Park Service says there have been no reports of wolves attacking humans in Yellowstone and recommends visitors stay at least 100 yards away from wolves.
