A disturbing incident occurred at Yellowstone National Park in Wyoming, involving a bull bison and visitors at a campsite. The bison charged and flipped a grandfather 8 feet into the air. A professional photographer captured the encounter and described the animal as appearing agitated.

The grandfather and his grandson were taking photos from a distance when the bison suddenly bolted towards them. They attempted to run and hide, but the bison caught up and hooked the grandfather with its horn.

Further details about the incident are available from the source, including an account from the photographer who witnessed the event and helped rush to the man's aid.
