A herd of bison halted traffic at Yellowstone National Park, footage posted to Facebook on April 18 shows.
The video, captured by Montana native Cindy Shaffer, was shared to the Yellowstone Unfiltered community Facebook group.
Shaffer captured the herd strolling by, seemingly oblivious to the traffic building up behind them. “Bison jam,” she quipped in the caption. Credit: Cindy Shaffer via Storyful
