A herd of bison stampeded within yards of a father and his children inside their car at Yellowstone National Park in July.
Ernie Santana and his family were visiting Wyoming Park when a vehicle in front of them stopped.
These images show why it stopped: a cloud of dust in the distance was followed by animals running past.
“We could literally feel the ground shaking as they passed by us. Some were so close to our car that I had to close the rearview mirror for fear of it breaking,” Santana said of the spectacle.
“We were worried about our rental vehicle being damaged and we had to explain that to our insurance company.”
