Occurred on May 22, 2021 / Yellowstone National Park, Wyoming, USA
Info from Licensor: "We were on a family drive in Yellowstone with my wife and our 4-year-old son, 2-year-old daughter, and my sister. We had turned around and started to look for a place to have a picnic lunch, while my son tried 'calling buffalo' so we could see more.
As I was driving I noticed an elk run out behind us with a wolf right behind it. In the quick glance in my mirror I thought it all happened behind the white car behind me."
