A hiker found dead on Friday in Yellowstone National Park was attacked by a grizzly bear, according to a news release from the park on Saturday afternoon.

"While the exact cause of death has not been determined, investigators have identified what appear to be defensive wounds on the victim’s forearms," the news release said.
The victim’s body was found partially consumed and cached, or covered, in the vicinity of the Elephant Back Loop Trail near Lake Village.
"Based on partial tracks found at the scene, it appears that an adult female grizzly and at least one cub-of-the-year were present and likely involved in the incident," according to the news release.
The name of the individual is being withheld pending family notification.
The Montana man was a long-term seasonal employee of Medcor, the company that operates three urgent care clinics in the park. He had worked and lived in Yellowstone for five seasons and was an experienced hiker.
He was reported missing on Friday morning when he did not report for work. A park ranger found his body in a popular off-trail area he was known to frequent, about a half-mile from the Elephant Back Loop Trail. Other rangers and wildlife biologists responded to the scene and gathered evidence for bear DNA recovery.
The investigation will continue, although heavy rains in the area Friday evening and Saturday morning have made additional evidence recovery difficult. A forensic autopsy is currently scheduled for Monday.
Wildlife biologists set bear traps in the area on Friday evening. If bears are trapped and identified as having been involved in the attack, they will be euthanized.
“We may not be able to conclusively determine the circumstances of this bear attack, but we will not risk public safety,” Park Superintendent Dan Wenk said. “We are deeply saddened by this tragedy and our hearts go out to the family and friends of the victim as they work to cope with the loss of someone who loved Yellowstone so very much.”
The Elephant Back Loop Trail and immediate area is closed until further notice. Signs are posted and maps of the closure area are available at park visitor centers.
All of Yellowstone National Park is considered bear country. Hikers are advised to stay on designated trails, travel in groups of three or more people, carry bear spray, be alert for bears, and make noise to help avoid surprise encounters.
