Overview
- A widely shared video shows 65-year-old Carl Isom-McDaniel being charged and thrown by a bull at Bridge Bay Campground on July 10, suffering a broken femur and undergoing surgery.
- Video from July 19 captured a fisherman nearly unaware of a bison approaching from behind until his wife and other parkgoers alerted him, allowing him to walk away without injury.
- A separate user video shows a bison ramming an SUV and popping a tire in Yellowstone; no injuries were reported in that encounter.
- Park officials and the U.S. Department of the Interior have reiterated safety rules that visitors must stay at least 25 yards from large animals and note that the rutting season increases bull aggression.
- Yellowstone houses the nation’s largest public bison herd and adult bulls can weigh about 2,000 pounds and run roughly 35 mph, factors that make close encounters dangerous and that have shaped officials’ choice to monitor rather than remove implicated animals.
