A photographer's video and account show a bull bison chasing a man around trees at Yellowstone's Bridge Bay campground, hooking him at the hip and tossing him about eight feet, while the Guardian reported that the National Park Service had released no details about this encounter by Sunday. [1]

Photographer Mike MacLeod said the man and his grandson had initially stood dozens of yards away and moved behind trees when the bison rose, but a witness estimate and video cannot establish a measured distance, an official injury diagnosis, visitor fault or the animal's motive. [1]

Yellowstone's verified X post states that visitors must stay at least 25 yards from large animals and calls bison unpredictable, yet it accompanied a different June 26 incident involving a 12-year-old near Mud Volcano and therefore proves guidance, not what happened at Bridge Bay.

Breaking911's same-day post supplies the viral eight-foot spectacle and repeats a serious-injury claim, but the account is an aggregator rather than a park or medical authority, and its mutable view count cannot convert circulation into confirmation.

The useful service distinction is simple: follow the park's distance rule and move away when wildlife approaches, while keeping this event in its narrower evidence lane until officials establish injuries, compliance, circumstances and any role for rut behavior, and keep any later park findings separate from the clip's fame.
