A family just happened to witness (and film) this incredible scene.

Michael Daus is a business owner in Jackson, Wyoming, and decided to take his family on a trek through Yellowstone National Park on May 31, 2020. The family enjoyed the day and got to see the beautiful natural wonders and wildlife that roam the park, including a grizzly bear that they saw on the road as they turned into the parking lot near the Grand Prismatic Overlook trail. Prepped with bear spray, the family felt safe enough to head out as they kept a safe distance from the bear. 

On the way back to the car, however, they encountered a situation that quickly became deadly.

The grizzly had moved closer to the parked vehicles while the family had embarked on their hike ... and he had company, a young bison. The bison made an attempt to charge at the bear and the hungry, far more experienced predator returned the charge. As the family walked to the car, Daus was able to film the entire encounter.

Daus can be heard explaining what is happening on the video while he remains far away. In all, he shot about 17 minutes of video then edited it down to a five-minute clip, "Bear v Bison," and posted it on YouTube. Watch the video below.

The video has been viewed over 270,000 times, at the time of this writing, and another edited version of it is featured on the Jackson Hole EcoTour Adventures Facebook page.

"We weren’t crazy about returning to find the bear so close,  just beyond the opposite side of the small parking area," said Michael Daus. "We didn’t even see it until we were at our vehicle. I was particularly relieved that the bear seemed more interested in the bison, so while very close to the car, we simply maintained what felt like a safe distance.

Having lived nearby for decades not minutes, we certainly don’t want our actions or the appearance of our proximity to the animals to set any kind of bad example about approaching wildlife. The camera on this phone boasts a pretty amazing lens and zoom capabilities. So I was able to get all the shots from further than it may appear. The kids enjoyed watching safely from the sunroof of the car."

Yellowstone is the home of many wild animals, and the grizzly bears in Yellowstone feed on bison. They, along with wolves, are the only predators of the bison in the park, though many animals and scavengers feed off the spoils.

Recently, in Boulder, Colorado, a young bear cub can be seen on video charging at the door of a family's home.

Have you ever been this close to an animal encounter like the one Daus filmed? It's a good reminder to always stay alert when interacting in nature, especially a place like Yellowstone where humans are guests in the home of these animals.
