Hypothetical question: how do you know if you've made it as a celebrity if you're a wolf? Answer: when National Geographic makes a movie about you. That's exactly what happened to one black wolf in Yellowstone National Park a few years ago.
It's been almost 8 years ago to the day when this famous wildlife encounter went down in Yellowstone National Park. A gray wolf attempted to take down an elk in a raging river in front of tourists with cameras rolling.
If you're fortunate, you might hear wolves howl next time you visit Yellowstone National Park. But, you're not likely to hear them all the way in downtown West Yellowstone unless you were there a few mornings ago.
I think it's safe to say that there are daily encounters between bears and wolves in Yellowstone. Some we can see, but most we don't. There was one battle a couple years ago that became more famous than most.
