Yellowstone National Park officials have decided against euthanizing the bull bison that tossed a 65 year old Washington man into the air during a campground encounter last week.
The animal acted in accordance with its natural instincts when it charged Carl Isom McDaniel at Bridge Bay Campground near Yellowstone Lake on the evening of July 10 around 8:30 p.m. Mountain Daylight Time. Park staff confirmed the bison will stay in the wild with no management intervention planned. Isom McDaniel suffered a broken femur in multiple places along with additional injuries but has undergone surgery and begun standing again while recovering. The encounter unfolded after the bull bison appeared calm then became agitated possibly by a passing truck before pursuing the man and his grandson around a cluster of pine trees.
Witness accounts describe the bull bison as visibly agitated before the incident. It had already charged at other campers including a group of teenagers earlier that evening. Isom McDaniel and his 13 year old grandson had paused to take photos from a distance before the animal pursued them around a cluster of trees. The bison hooked the man near the hip and launched him roughly eight feet into the air. Bystanders including professional photographer Mike MacLeod intervened by yelling and approaching to drive the animal away until park emergency responders arrived about 10 minutes later.
National Park Service guidelines consistently remind visitors to maintain at least 25 yards from bison and recognize signs of agitation such as head bobbing or raised tails. Bison rank as the leading cause of injuries to people in the park because of their size speed and power especially during the summer rut when testosterone levels rise. This event marks the second reported bison related injury in Yellowstone this year and underscores the need for constant awareness around wild animals that weigh up to 2000 pounds and can outrun humans.
Park officials took the decision to take no action against the bison after reviewing the incident and determining it behaved naturally within its habitat. This determination came from Yellowstone National Park staff who prioritize wildlife protection alongside public safety. Officials emphasize that bison remain free roaming symbols of the American West rather than managed threats unless they pose repeated risks. This approach aligns with broader conservation efforts to protect one of the last significant wild herds in the United States.
The incident has renewed conversations about responsible tourism in national parks where natural encounters carry inherent dangers. Visitors bear primary responsibility for safety by respecting posted distances and heeding warnings during peak seasons. Isom McDaniel himself later noted the bison could have caused far worse harm while he lay on the ground yet chose not to press the attack further.
