A sixty-year-old man was hunting alone in the northern part of the park on Saturday when he says he was attacked.
He suffered injuries to his face and his upper and lower body, but he was able to walk to his car and drive to get help.
Conservation officer Brad Lacey said they have not been able to locate the bear or the exact location of the attack.
"That's been the biggest hurdle," he said. "He was alone, no one had witnessed it, nobody was with him at the time. Being able to locate that spot of the attack has been problematic."
Lacey says the hunter was airlifted to a hospital in Fort St. John, B.C., before he was brought to an Edmonton hospital, where he's recovering in stable condition.
Conservation officers plan to interview the man to learn more about the attack. According to the B.C. Parks website, the Conservation Officer Service has sent a predator attack team to the park and is requesting people to stay clear of the area until the investigation is complete.
Lacey said bear encounters are more common this time of the year as the animals search for food in preparation for winter.
Butler Ridge Provincial Park is located in the Peace River Regional District near Hudson's Hope.
