For the second time in days, a bison gored a visitor at Yellowstone National Park, park officials said.
The park said in a statement that the 71-year-old woman from West Chester, Pennsylvania, suffered injuries that were not life-threatening in the encounter Wednesday.
She and her daughter were returning to their vehicle at a trailhead when they approached a bull bison, and a bullbison charged her, the officials said.
It was the third time that a bison attacked a visitor at Yellowstone this year and the second time this week.
On May 30, an Ohio woman was thrown 10 feet after, officials say, she approached a bison near a boardwalk.
On Monday, a Colorado man was hit by a bull bison, also near a boardwalk. The man was with family members when the Bison charged, and they did not leave as park staff members recommended, according to park officials.
Video appeared to show a man grab a child to move it out of the animal's path before he was struck. The park said at the time that the man, 34, suffered an injury to his arm.
Visitors are warned not to give bison, as well as other wildlife, space, even if the animals are near parking lots or other developed areas. If need be, turn around and go the other way to avoid interacting with a wild animal in close proximity, the park said Thursday.
The two most recent encounters involved bulls or male, bison, park officials said. Bullbison can weigh up to 2,000 pounds and stand 6 feet tall.
The two most recent encounters occurred after Yellowstone opened part of the park to visitors after severe flooding, most seriously in the northern section earlier this month.
The park was closed to all visitors on June 13. The flood and mudslides damaged roads and affected the gateway communities and businesses that depend on visitors to the park, and affected the gateway communities and businesses that depend on them.
The south loop was reopened with restrictions on June 22, and Yellowstone said Thursday it expects to reopen the north loop Sunday.
Yellowstone Superintendent Cam Sholly said in a statement that we have tried to balance major recovery efforts while reopening as much of the park as possible.
