A woman captured the moment she stayed calm - as a family of bison charged towards her car.
Passenger Marisah Yazbek, 29, was on a road-trip to Montana, USA, with her friend Alina Ezzi.
The friends from California, USA were travelling through Yellowstone National Park in Wyoming when the herd of bison approached the road.
A video shows the moment panic sets in for Alina and absolute calmness for Marisah as the animals make their way across the road.
Marisah, a producer from Temecula, California, said the incident "made for a perfect look at what the friendship dynamic is like between the two."
She added: "We were on vacation, making a few stops on our scenic route to Montana.
