A bison charged at a man who was approaching the animal from behind at Yellowstone National Park on Wednesday, April 20.
Video recorded by Sean Swetter shows the bovine burst towards the man near a walkway at Geyser Hill, a popular hot spring site in Yellowstone National Park.
Swetter posted this video to the Facebook group Yellowstone National Park: Invasion of The Idiots!, a page critical of the behaviour of tourists at the national park.
In the post, Swetter described the event as a “narrow escape”. Credit: Sean Swetter via Storyful
