Imagine what you would do in this situation. You're a deer (I realize that's a reach) and you're being chased by a coyote. What do you do? If you're in Yellowstone National Park, you hide in a nearby bison herd which is exactly what just happened as a new video shows.
I am a confessed earthquake and geology nerd which is why I find the ecosystem of Yellowstone National Park fascinating. You might be interested to know there have been at least 178 earthquakes within the park over the past week, but you really shouldn't worry.
There is always an uneasy peace between bears and wolves in Yellowstone National Park. That was witnessed by guests (and workers) in the park a few days ago as a grizzly and two wolves came face-to-snout in a showdown in Hayden Valley.
