In a nerve-wracking incident at Yellowstone National Park, two tourists had a close call with a bison after ignoring repeated warnings to steer clear of the area.

A wildlife photographer captured a dramatic video showing how the pair narrowly escaped danger in the renowned park, which stretches across nearly 4,000 square miles in the states of Wyoming, Montana, and eastern Idaho.

During their late-May adventure, the reckless duo was spotted on a grassy patch at Grizzly Hill, standing perilously close to a bison.

The tourists casually walked away as the massive animal followed them at a slow pace, despite onlookers urging them to leave the scene immediately.

Pandemonium ensued when the bison suddenly charged at them, escalating the situation into a frightening ordeal.

‘Look out!’ the photographer, Julie Argyle, Argyle screamed as the pair started running. The man ran ahead of the woman, staying out of the bison’s path, while the woman’s shirt appeared to get briefly caught on its horn. 

Luckily for the brazen tourists, the bison ran past them. 

‘Slide down the damn hill,’ one baffled woman yelled at the couple who were still lingering in the vicinity in the moments after the terrifying run-in. 

‘Ten minutes before this happened, we asked these people not to go up the hill because the bison were roughhousing,’ Argyle wrote when she posted the video on Facebook over the weekend.

‘The man turned and flipped his hand at us, basically brushing us off.’ 

The photographer elaborated in the video’s caption, urging others to take the incident as a warning.

‘Most of the time when you’re asked not to do something in Yellowstone, it’s for a good reason,’ Argyle wrote.

‘Please be mindful if someone asks you not to do something. It’s usually for your own good.’ 

There are roughly 5,400 bison across Yellowstone, according to a 2024 estimate from the National Park Service (NPS). 

Male bison can weigh up to 2,000 pounds, while females can weigh up to 1,000 pounds. 

The NPS described the animals as ‘aggressive’ and ‘agile,’ noting that they can run at speeds reaching 30mph. 

Yellowstone is the only place in the lower 48 states that has had a free-ranging bison population since prehistoric times. 

‘There’s an imaginary sense of safety in Yellowstone,’ bison advocate George Wuerthner told the Cowboy State Daily in September. ‘People tend to look at the wildlife in Yellowstone like they would if they were at a zoo.’

‘Those animals are accustomed to people, but that doesn’t negate their wild tendencies,’ he continued. ‘In their wild conditions, Yellowstone’s wildlife will react differently than an animal in the zoo.’

Argyle, who frequents the park to watch and photograph its animals, told Cowboy State Daily that she believes visitors are losing respect for Yellowstone’s inhabitants. 

‘I tell people not to get too close to animals all the time, and I get yelled at. Foul words are yelled at me all the time,’ she explained. 

‘I believe people don’t realize the true consequences of their actions, but I definitely think they’re doing things and not caring about what could happen.’

Argyle’s sentiment appears to be true, with multiple instances of bison goring people at Yellowstone in recent history. 

In May, a bison charged into a 47-year-old man from Florida, who came within 10 feet of the animal near Yellowstone Lake and Old Faithful. 

He was treated on-site by park emergency personnel and did not require hospitalization, the NPS said. 

In 2024, an 83-year-old woman was lifted off the ground by a bison’s horns near the Storm Point Trail.

A year earlier, a 47-year-old woman sustained serious chest and abdominal injuries after being gored near Lake Village.

A 25-year-old woman died in 2022 after a bison gored her at the park and threw her 10 feet into the air. Just weeks later, a 1,800-pound bison gored a 34-year-old man who rescued a little boy in the beast’s path.

On average, there are only one to two bison-inflicted injuries reported at Yellowstone each year. Bison are responsible for more injuries at the park than any other animal. 

From 2000 to 2015, 25 visitors were harmed in a bison encounter. Only two people have died from run-ins with a bison in Yellowstone since 1972.  

Park officials constantly stress the importance of maintaining a safe distance – 25 yards from large animals like bison – to protect visitors.
