Occurred on October 2, 2018 / Yellowstone National Park, Wyoming, USA
Info from Licensor: "This video was taken on the road between Canyon Village and Norris in Yellowstone National Park. After finishing the Cascade Lakes hike, I was returning to the Old Faithful Inn where I saw a few cars stopped. That's where I recorded the video. I was there for perhaps 10 minutes. Sadly, for the people heading in the opposite direction, they were delayed over 2 hours, I heard."
