The woman approached the bison to take a photo and got less than 10 feet from her several times before gutted her on June 25, the statement said.
She suffered multiple goring injuries and was treated by rangers before being transported east to Idaho Regional Medical Center for further treatment.
The statement said the woman approached the bison several times near her campsite at the Bay Bridge Campground in northwest Wyoming before the loaded bison.
“The series of events that led to the goring suggest the bison has been threatened by being repeatedly approached within 10 feet,” Yellowstone senior bison biologist Chris Geremia, said in the statement.
“Bison are wild animals that respond to threats by displaying aggressive behaviors like scratching the ground, sniffing, diving their heads, bellowing, and raising their tails. If it doesn’t make the threat (in this case, it was a person) move away, a threat of bison can impute, “added Geremia. “To be safe around bison, stay at least 25 yards, who is approaching, and run away or find cover if they are in charge. “
The attack serves as a reminder that “the wildlife in Yellowstone National Park is a savage,” according to the release.
Park visitors must stay 25 yards from all the large animals in the park, including bison, elk, bighorn sheep, deer, moose and coyote, the statement said. If people meet bears and wolves, they should stay 100 yards away.
