A bull bison charged a retiree at a Yellowstone National Park campground Friday night, hooked him near the hip with its left horn, and flung him roughly eight feet into the air, an attack captured on camera that has since gone viral. The victim, Carl Isom-McDaniel, a grandfather in his mid-60s from Kendall, Washington, suffered multiple broken bones. He was conscious the entire time and, by all accounts, cracking jokes while he waited for the park ambulance.
The incident unfolded at Bridge Bay Campground near Yellowstone Lake, in the park's southeast quadrant, during what witnesses described as an already tense evening. The bison had been menacing groups of visitors well before it turned on Isom-McDaniel and his unnamed grandson.
Bozeman, Montana-based professional photographer Mike MacLeod witnessed the full sequence and told the New York Times the animal was agitated long before the grandfather arrived on the scene. Yellowstone's own regulations require visitors to stay at least 75 feet from bison, a rule that takes on special weight during mating season, when bull bison are territorial and unpredictable.
MacLeod's account paints a picture of escalating danger that went largely unheeded. Before the attack on Isom-McDaniel, the bison had already scattered a small group of teenage boys by charging at them. After that confrontation, the animal settled in the dirt near a picnic table just off a campground road still covered in dinner leftovers.
It didn't stay calm for long. MacLeod described the bison's body language as "really, really angry," its head rearing up and down in an aggressive manner. He told the New York Times:
"It was kicking like a rodeo horse who's clearly very agitated."
Then the bison stopped rolling in the dust and locked onto new targets. MacLeod recounted the moment:
"The bison stopped rolling in the dust and kind of sat up. He's looking in the direction of those two."
"Those two" were Isom-McDaniel and his grandson, who had stopped to photograph the animal, apparently unaware of what had already happened with the teenagers. A pickup truck had driven by, briefly drawing the bison's attention. When Isom-McDaniel and his grandson paused to take pictures, the bison was still sitting. But the moment they stopped, the animal stood.
MacLeod recalled what happened next:
"And as soon as they stop taking pictures, the bison stands up and the grandfather's like, 'Let's get out of here. I don't like this.'"
It was already too late. A second pickup truck passed and momentarily distracted the bison, but once the vehicle was out of sight, the animal turned back toward the grandfather and his grandson.
The bison chased both of them around a copse of pine trees. The grandson escaped with what MacLeod described as "some fancy footwork." Isom-McDaniel was not as lucky. The bull caught him, drove its left horn into the area near his hip, and launched him approximately eight feet off the ground.
What happened next says something about the kind of people who still visit America's national parks. MacLeod put his camera down and ran straight at the bison.
"I put my camera down and I ran at the bison pumping my arms up and down, yelling at the top of my lungs and jumping up trying to look big and distracting."
Other park visitors joined in. The bison eventually fled the scene. Fellow tourists stayed at Isom-McDaniel's side until a park ambulance arrived roughly 10 minutes later and transported him to a hospital. The specific hospital was not identified.
The incident is a reminder that wildlife encounters can turn dangerous without warning, whether it's a national park campground or a New Jersey lake.
The man at the center of the viral footage is no thrill-seeker. Isom-McDaniel is a retiree from Kendall, Washington, described as a fixture in his local community. He serves on several boards, including water and parks commissions, and chairs a local community newsletter. He was visiting Yellowstone with his grandson, a family trip, not an adventure stunt.
Despite the severity of the attack, multiple broken bones and a horn strike near his hip, MacLeod said Isom-McDaniel stayed in remarkably good spirits.
"He was in a lot of pain with his leg, and otherwise he was conscious the whole time, in good spirits, joking."
That combination, a civic-minded grandfather who volunteers on local boards, takes his grandson to Yellowstone, and cracks jokes while waiting for an ambulance after being gored, tells you something about the man's character.
Yellowstone requires visitors to maintain at least 75 feet of distance from bison. The rule exists for exactly this reason. Mating season, which coincides with the peak of Yellowstone's tourist season, makes bull bison especially volatile, "likely hopped up on testosterone," as the reporting characterized the animal's state.
But enforcing a 75-foot buffer in a campground where bison wander freely past picnic tables and roads is a different matter. The bison that attacked Isom-McDaniel had been resting just off a campground road. It had already charged teenagers. It had already displayed textbook aggressive behavior. And yet no park intervention is mentioned before the attack occurred.
Whether park rangers responded to the scene at all remains unclear. Whether the bison was later tracked or subjected to any management action is also unknown. Those are questions worth asking, especially as Yellowstone enters its busiest stretch of the year.
Sudden, violent encounters between people and wildlife are not limited to national parks. A toddler dragged underwater by an otter at a Washington marina prompted a six-figure settlement from the Port of Bremerton, raising similar questions about whether officials did enough to protect the public from known hazards.
MacLeod, a professional photographer who lives near the park, clearly recognized the danger before the attack. He watched the bison's body language escalate. He saw it charge the teenagers. He described it as "really, really angry." And yet he also watched Isom-McDaniel and his grandson walk into the situation without realizing what they were stepping into.
That gap, between what experienced observers see and what ordinary visitors understand, is where most of these incidents happen. The grandfather sensed something was wrong. He told his grandson to leave. But the window had already closed.
Tragic accidents in public spaces often follow this pattern: warning signs visible in hindsight, an ordinary person in the wrong spot at the wrong moment, and a response that arrives after the damage is done. The same dynamic played out when a Delta employee was killed by a tug vehicle at Orlando International Airport, a sudden catastrophe in a place people assume is safe.
Isom-McDaniel's current condition beyond "multiple broken bones" has not been publicly disclosed. His grandson was not injured. MacLeod's photographs and footage have circulated widely, turning a campground evening into a national news story.
Several questions remain open. What hospital treated Isom-McDaniel, and what is his prognosis? Did Yellowstone rangers take any action regarding the bison after the attack? Was the animal already known to park staff as a problem? And what, if anything, is the park doing to warn visitors at Bridge Bay Campground during the current mating season?
None of those answers have surfaced yet. What has surfaced is a viral video, a grandfather with broken bones, and a photographer who dropped his camera to save a stranger.
America's national parks belong to the public. The public deserves to know whether the people managing those parks are doing enough to keep a campground from becoming a rodeo arena, with unarmed retirees as the main event.
