  • On the afternoon of Tuesday, Sept. 16, a male, age 29, sustained injuries from a bear while hiking on the Turbid Lake Trail, located northeast of Mary Bay in Yellowstone Lake.
  • The incident occurred approximately 2.5 miles from the Pelican Valley Trailhead in the Pelican Valley Bear Management Area.
  • The male was hiking alone when he encountered the bear near Turbid Lake.
  • The hiker began to deploy bear spray when the bear made contact, and he sustained significant but non-life-threatening injuries to his chest and left arm.
  • National Park Service medics responded to the incident and walked out with the hiker.
  • Once arriving to the trailhead, NPS transported the hiker in a park ambulance to the Lake Medical Clinic.
  • He was then flown to a nearby hospital for treatment.
  • The hiker thought the bear was a black bear; however, the location, size, and behavior of the described bear suggest it might have been a grizzly bear.
  • Bear management staff will attempt to confirm the species through DNA analysis, if possible.
  • The Turbid Lake Trail is closed until further notice. 
  • Bear management staff are sweeping the trail to ensure no other hikers are on the trail.
  • Because this incident was a defensive reaction by the bear during a surprise encounter, the park will not be taking any management action against the bear.
  • This incident remains under investigation and there are no further details to share at this time.
  • This is the first incident of a bear injuring a person in Yellowstone in 2025.
  • The last incident was in May 2021 when a grizzly bear injured a solo hiker on the Beaver Ponds Trail in Mammoth Hot Springs.
