A video making the rounds on social media recently showed tourists running from a black bear and her cubs in Yellowstone National Park. Unfortunately this is not the first nor probably the last time that animals and people have collided at the park. Here is a collection of some of the most dramatic encounters at Yellowstone caught on video.

The following video uploaded in March 2015 shows a buffalo ramming a car at 200 yards. It might be time for a new bumper.

In this 2012 video, a bull elk during the autumn rut near mammoth hot springs is seen ramming cars as they stop to get a look at all the commotion.

In this classic video, a buffalo is seen chasing tourists around a grove of trees in a terrifying encounter near the Old Faithful Geyser.

Lastly, here is a bison ramming a minivan.
