Zookeeper Jack Hanna Uses Pepper Spray to Save Hikers From Bear

July 27, 2010 — -- What if you came in close contact with a pack of grizzly bears: Would you run? Scream? Just stand still and hope for the best?

Well, if you're Jack Hanna, the world-renowned animal expert and zookeeper, you know exactly what to do: grab your pepper spray.

"My heart was pounding Saturday night, I'll tell you that," Hanna told ABC News' Diane Sawyer.

At around 2 p.m. Saturday, Hanna and his wife Suzi were trekking up Montana's Glacier National Park, a location he said they have frequented for more than 20 years.

As they approached a corner within a section of the park called Grinnell Glacier, the two hikers, along with two other groups of hikers, encountered a mother grizzly and her offspring just 30 feet away.

"Here comes a mama and yearlings, not cubs," Hanna recounted. "Yearlings are about 100 to 150 pounds. You cannot run from these animals. They run a football field in six seconds."

After advising the other hikers to slowly walk back on the six-foot-wide trail for what "[seemed] like an hour," and also taking into account the cliff with a 1,000 foot drop on their other side, Hanna knew that his pepper spray eventually would be their ticket to safety.

But before Hanna even drew his can, the mother and one of the yearlings passed by, leaving the other just 10 feet away. It was not until the bear started getting closer to the hiking group that Hanna took action and sprayed the animal.

"I unloaded the first blast and the wind blew the damn pepper spray right away," said Hanna. "He's still coming, so I blast him again about 15 feet and he's still [coming], 'roar', and he goes like that about 10 feet right in front of me. I had the pepper spray right in his face. I mean, I could just [have said] this is it for me. I just go 'pssssh' and unload the whole thing in his face.

"That's why I waited so long for that first blast of pepper spray, because I didn't want that yearling squealing for his mom, and the mom comes back and [says], 'I'm going to kick somebody's butt here,'" Hanna said. "I didn't want it to be my butt."
