Grandfather knocked airborne by bison in Yellowstone National Park

A man and his grandson were pursued by a bison after the animal closed the distance that initially seemed safe. The encounter, reported by local authorities, took place in a wildlife‑recreation area where bison are known to roam freely, and the pair were forced to flee as the large mammal rapidly accelerated toward them.

Emergency responders arrived shortly after the chase, providing medical assistance to both individuals, who sustained minor injuries. Officials reminded visitors that bison can be unpredictable, advising people to maintain a substantial buffer, avoid sudden movements, and follow park signage. The bison was later observed moving away from the scene without further incident, and authorities emphasized continued public education to prevent similar encounters.
