Photographer Describes Bison Attack on Grandfather in Yellowstone

A photographer who recorded a video of a grandfather being attacked by a bison at Yellowstone National Park spoke to CNN on July 14. Mike MacLeod, who was camping in the park, described how the bison charged at a group of boys before chasing a young couple from their campsite. When the grandfather and his grandson approached the area, the bison charged at them, resulting in the grandfather being thrown into the air. MacLeod noted that the time of year, coinciding with the beginning of bison mating season, may have contributed to the animal's aggressive behavior. After the incident, MacLeod and other campers helped to move the bison away from the area. The victim, Carl Isom-McDaniel, sustained several broken bones but was concerned about his grandson, who was unharmed. This incident marks the second bison attack reported in Yellowstone this year.
