The woman and her daughter accidentally approached the bison as they were returning to their vehicle at the top of the trail, causing the animal to charge, according to a statement from the park inspector. The woman suffered non-life-threatening injuries and was taken to a Wyoming hospital, according to the statement. The park notes that bison have injured more people in Yellowstone than any other animal. The NPS said bison are unpredictable and can run three times faster than humans. The park service asked visitors to stay at least 25 meters away from large animals. Another attack came just a day earlier Monday when a 34-year-old Colorado man was eaten by a bison in the park after walking with his family on a sidewalk near Giant Geyser in Old Faithful. When the family members did not leave their area, the bison bull “continued to load and devour” the man, causing injury to his hand, park officials said. The man was taken to hospital and the incident is being investigated. A 25-year-old Ohio woman was also devoured by a bull in late May, the first reported incident this year. The woman suffered a puncture wound and other injuries after approaching a bison near a sidewalk in the Black Sand Basin, according to a previous press release. He threw it 10 feet into the air from a bison after it reached a distance of 10 feet from the animal, park officials said. Two other people were also 25 feet away from the same bison, they added.
