Boy injured by bison in Yellowstone

Yellowstone, Wyo. – A 12-year-old boy from Pennsylvania was hospitalized after he was flipped into the air by a bull bison at Yellowstone National Park.

Park officials say witnesses reported that the boy was posing Thursday with members of his family within 1-2 feet of the mature bull bison. The bison flipped the boy about 10 feet in the air.

The incident occurred on a trail near the Grand Canyon of the Yellowstone.

Although the boy's visible injuries were limited to abrasions, he complained of abdominal pain. He was flown to the Eastern Idaho Regional Medical Center in Idaho Falls.

Authorities are not releasing the boy's name or hometown and no information is available on his current medical condition.

Park rules require visitors to remain at least 100 yards from bears or wolves, and at least 25 yards from all other animals.
