Caught on Camera: Raging Yellowstone Bison Hooks Grandfather and Launches Him 8 Feet Into the Air

A routine summer visit to Yellowstone National Park turned into a horrifying nightmare Friday evening when a massive bull bison at Bridge Bay Campground locked onto a grandfather tourist and launched him approximately 8 feet into the air after hooking him with its horn — and the whole terrifying ordeal was captured on video by professional wildlife photographer Mike MacLeod, who was already filming the animal's increasingly erratic behavior. MacLeod described the bull as "angry, agitated and charging anything and everything" in the moments before the attack, a chilling eyewitness account that underscores just how quickly an encounter with a 2,000-pound wild animal can spiral from alarming to life-threatening. The grandfather and his young grandson had been standing well over 100 yards away from the animal — far beyond the 25-yard minimum distance Yellowstone requires visitors to maintain from bison — making the sheer explosive range and unpredictability of the charge all the more shocking to witnesses on the scene.

Wildlife experts and park rangers point to an all-too-familiar seasonal culprit: bison rut season, which peaks in July and August and transforms normally imposing bulls into powder kegs of aggression, territorial fury, and hair-trigger violence. During rut, bull bison have been documented charging vehicles, trees, fences, and anything else unlucky enough to enter their line of sight — and according to MacLeod, a passing truck in the area may have been the initial trigger that sent the animal into its charging frenzy before it zeroed in on the grandfather and his grandson. The victim was seriously injured and required emergency medical attention, with the full extent of his injuries not immediately disclosed by park authorities. It is a brutal reminder that Yellowstone is not a zoo — the animals are wild, unpredictable, and fully capable of killing a human being in seconds.

MacLeod's footage is already spreading rapidly across social media, delivering a visceral, unfiltered look at the raw danger that lurks in America's most beloved national park for visitors who underestimate the wildlife around them. Yellowstone officials have repeatedly warned tourists about maintaining safe distances from bison, citing a pattern of attacks that spikes every summer as millions of visitors descend on the park during peak season — and yet each year the warnings are ignored, often with devastating consequences. This latest attack stands as yet another urgent wake-up call: no matter how peaceful and majestic a bison may appear grazing in an open meadow, it remains one of the most dangerous animals on the North American continent, and the park's wilderness demands respect, distance, and constant vigilance from every visitor who enters its gates.
