A grandfather suffered a broken hip after a bull bison charged and hurled him eight feet into the air at Yellowstone National Park, according to witnesses and park officials. The attack occurred on July 10, 2026, at the Bridge Bay Campground in Wyoming, despite the victim and his grandson maintaining what onlookers described as a safe distance of about 100 yards from the animal.
Unprovoked Attack Captured on Video
The incident was recorded by Mike MacLeod, a former Army combat photographer staying at the campground. MacLeod reported that the bison appeared "angry, agitated, and charging anything and everything" before targeting the grandfather. Earlier, the bull had rushed at a group of young photographers and charged a passing white pickup truck.
According to MacLeod, the grandfather and grandson initially sought refuge behind a small cluster of pine trees when the bison became restless. However, the animal crashed through the trees and pursued the pair. While the grandson escaped unharmed, the grandfather was caught, with the bison driving its left horn into his hip and launching him into the air. MacLeod described the victim executing a "perfect flip" before landing heavily on his side.
Emergency Response and Injuries
Onlookers rushed to help, shouting and charging at the bison to drive it away. Emergency services provided first aid at the scene. The man sustained a broken hip and remains hospitalized in serious condition, according to reports.
The National Park Service guidelines recommend staying at least 25 yards away from bison, but the victim was reportedly about 100 yards away, far exceeding this advice. The attack highlights the unpredictability of wildlife, particularly during mating season.
Bison Mating Season Underway
The attack occurred during the annual bison mating season, known as the "rut," which runs from July through September. During this period, bull bison experience surging testosterone levels, making them highly volatile and territorial. Experts advise avoiding eye contact and maintaining a steady pace when encountering bison during this time.
This incident serves as a reminder of the dangers posed by wildlife in national parks, even when visitors follow safety guidelines.
