A bison gored a woman and tossed a teenager in the air at the Yellowstone National Park in two separate encounters with the enormous animals during tourist season at the national park, according to ABC News.

A sixty-eight year old woman from Georgia was rushed to a hospital after she was attacked by a bison during a hike on Storm Point Trail on Wednesday, the National Park Service said.

The beast charged towards her as she passed by and gored her, causing severe injuries. A witness reported the incident to a nearby ranger, who then called for help. Due to the serious nature of her injuries, the woman was airlifted to a nearby hospital. Her condition was not immediately known, CNN reported.

The other incident took place on June 23, when a 19-year-old girl came across a bison after she went off-trail after dark in the Lower Geyser Basin area.

The park's public affairs office said the Georgia girl and her three friends were returning to their car after swimming in the Firehole River late at night. The girl and a companion were walking in the dark when they came upon a bison lying down about 10 feet from them. The companion turned and ran from the bison, but before the woman could react, the bison charged her and tossed her in the air. She was taken to a hospital, reported Yellowstone Gate.

The teen's friends then took her home, where she woke up from her sleep complaining that she wasn't feeling well and medical help was called for. She was then taken back to a hospital in an ambulance where she was treated and released with minor injuries.

Park regulations require visitors to maintain a minimum distance of 25 yards (23 m) from all large animals including bison, elk, bighorn sheep, deer, moose, coyotes and at least a 100 yards (91 m) from bears and wolves.
