Overview
- A bull bison at Bridge Bay Campground charged and hooked a man in his mid-60s, launching him roughly 2.4–2.5 meters into the air during an encounter recorded on video on Friday, July 10.
- The victim, identified in reporting as Carl Isom-McDaniel, suffered multiple fractures, underwent surgery and remains hospitalized but conscious during recovery.
- Photographer Mike MacLeod filmed the attack and said he and other campers distracted the agitated bison so park medical teams could reach and evacuate the injured man.
- The National Park Service has repeatedly urged visitors to keep recommended distances from wildlife but had not released a detailed incident report during the recent coverage period.
- Experts and witnesses link the attack to rut-season male bison territoriality, a seasonal pattern that increases unpredictability and has contributed to other bison injuries in Yellowstone this year.
