A 71-year-old woman was gored by a bison at Yellowstone National Park just 2 days after a bison charged at a man near Old Faithful

• A 71-year-old Pennsylvania woman was gored by a wild bison at Yellowstone National Park on Wednesday.
• She "inadvertently" approached the animal before it charged. She sustained non-life-threatening injuries.

A 71-year-old woman was gored by a bison at the Yellowstone National Park on Wednesday — the second incident of its kind in just two days.

Park officials said in a statement that the woman, who was not named, was visiting Yellowstone from West Chester, Pennsylvania, with her daughter prior to the encounter with the bison on June 29.

"The woman and her daughter inadvertently approached the bison as they were returning to their vehicle at the trailhead, causing the bull bison to charge," park officials said in the Thursday statement.

They added that the woman was transported to a nearby hospital in Cody, Wyoming, for treatment after sustaining non-life-threatening injuries.

The Wednesday incident marked the third time this year that a park visitor had an unfortunate encounter with the national park's wildlife. On June 27, a 34-year-old man from Colorado Springs, Colorado, was gored by a bull bison near Giant Geyser at Old Faithful.

A 25-year-old woman from Ohio was also approached by a bison on the morning of May 30 near a boardwalk at the Black Sand Basin, where she was gored by the animal and tossed 10 feet into the air, sustaining a puncture wound and other injuries.

Officials with the national park warned visitors to stay at least 25 yards away from all large wild animals found on the grounds, including bison, elk, bighorn sheep, deer, moose, and coyotes, and at least 100 yards away from bears and wolves.
