A grandfather's walk through a Yellowstone campground turned violent when a bull bison suddenly charged and sent him flying an estimated 8 feet into the air, a witness says. Photographer Mike MacLeod, who was camping at Bridge Bay Campground on Friday, told the Cowboy State Daily he'd been filming the agitated animal from a distance as it moved through the area, at one point rushing a group of children who scattered. The National Park Service has not yet released details on the incident.

MacLeod says the man, identified by the New York Times as Carl Isom-McDaniel, and his grandson were roughly 100 yards away—about the distance Yellowstone recommends—when they paused to take photos of the bison, which appeared to have calmed down. A passing pickup seemed to set the animal off again, MacLeod told the Cowboy State Daily, and it then charged into the trees where the pair tried to hide. The grandson escaped, but MacLeod says, "The bison hooked him with his left horn on his hip and tossed him in the air. He made a perfect flip and landed on his side. The bison was at least 6 feet tall, and (Isom-McDaniel) was several feet above him." (Video here.)

MacLeod and others ran toward the animal, yelling, prompting it to bolt. Isom-McDaniel was taken away by Yellowstone EMS with multiple broken bones and what his grandson later described as "significant injuries." MacLeod maintains the visitors kept a safe distance and that the bison, likely amped up by rutting season, was the clear aggressor. "Most people see that these two did not ask for it," he tells the Times.
