In brief
During the busy July season in Yellowstone National Park, a massive bull bison charged a 65‑year‑old man named Carl Isom‑McDaniel and his grandson, propelling the older man several metres into the air. The attack left Isom‑McDaniel with serious injuries that required hospital treatment. Witnesses documented the event on video, capturing the bison’s sudden jump and relentless pursuit. Park officials advise visitors to keep a minimum of 25 yards distance from bison and warn that these animals are responsible for more injuries than any other wildlife in the park. The incident underscores the heightened risk during the bison mating season, when testosterone levels increase aggressive behaviour.
During a busy July evening at Bridge Bay Campground near Yellowstone Lake, a 2,000‑lb bull bison sprinted toward a 65‑year‑old man, Carl Isom‑McDaniel, and his grandson. The bison struck the grandfather with its head, sending him flying several metres into the air before crumpling onto his side. Witness videographer Mike MacLeod recorded the moment, noting that Isom‑McDaniel, though shocked and in pain, remained aware and kept a sense of humour throughout the ordeal.
Isom‑McDaniel sustained multiple injuries and was transported to a hospital. The National Park Service has yet to disclose detailed information, while the BBC has requested comments. Yellowstone’s own safety guidelines remind visitors to keep at least 25 yards distance from bison and never approach them to take photos.
This incident occurs amid exactly the peak season for both the park’s 60 % of annual visitors and the bison’s mating period, when males’ testosterone spikes lead to unpredictable aggression. Laramie Foothills Bison Conservation Herd’s lead scientist, Jennifer Barfield, cautions that the behavioural changes during breeding season heighten risk for hikers and campers alike.
The bison, after flopping on its side and launching itself into a brief jog, continued toward the couple, prompting them to flee through a nearby thicket. A white truck that approached at the last moment could not avert the charge, and its driver fled upon seeing the bison sprint toward the vehicle.
Relatives and park officials await fuller updates on the victim’s recovery and the overall circumstances surrounding the aggressive encounter. In the meantime, the incident serves as a stark reminder of the importance of respecting wildlife boundaries in cherished natural spaces.
