A married couple was injured by a bison while taking photographs on a boardwalk in Yellowstone National Park on Wednesday morning.

According to the park, the two were hurt after being “butted” by a bison at Mud Volcano, just north of Lake Village.

Theodore Schrader, 74, and Patsy Holmes, 72, from Heber City, Utah, were taking photographs when a bison approached them.

The bison butted Holmes, who then fell into Schrader and both fell to the ground.

Park rangers responded immediately and evacuated the couple from the trail, taking them a quarter mile to the road. They were then taken to the Lake Clinic.

Holmes was flown to Idaho Falls to be treated for her injuries. She was in stable condition as of Wednesday. Schrader had minor injuries.

Neither of the two were cited.

This is the first confirmed incident of a bison injuring visitors in 2017.

In 2015, five people were injured after approaching bison.

Whether an animal is near a trail, boardwalk, parking lot or in a developed area, park visitors are urged to give the animals space.

Stay at least 25 yards away from large animals like bison, elk, bighorn sheep, deer, moose and coyotes and at least 100 yards away from bears and wolves.
