Grandfather Saves Grandson During Terrifying Bison Attack at Yellowstone: What We Know

A Washington grandfather became an unlikely hero on July 10 when a charging bull bison at Yellowstone’s Bridge Bay Campground forced him to make an instant, life-changing decision. Carl Isom-McDaniel, 65, was photographing wildlife with his 13-year-old grandson when the animal suddenly charged. Without hesitation, he told his grandson to run back down the road while he deliberately positioned himself in front of the bison to distract it. The animal launched him approximately eight feet into the air, and the impact broke his femur in four places. From his hospital bed, Carl’s first concern wasn’t his own injuries—it was his grandson’s safety.

The incident was captured on video by professional photographer Mike MacLeod, who holds a master’s degree in wildlife biology. MacLeod didn’t just film the attack; he actively helped by running toward the bison and yelling to distract it, preventing further injury to Carl. His quick thinking and presence of mind may have made the difference between a bad situation and a tragedy. The bison involved in the attack was not euthanized, and wildlife officials have used the incident to reinforce park safety guidelines.

What makes this story especially important right now is timing. Bison at Yellowstone are currently in their aggressive mating season, known as the rut, which runs through summer. During this period, these animals are significantly more dangerous and unpredictable than usual. They can run three times faster than humans and have injured more Yellowstone visitors than any other animal in the park. Park officials emphasize maintaining at least 25 yards of distance from bison at all times and never assuming an animal is safe to approach just because it appears calm.
