A 17-year-old girl snowmobiling with a group southwest of West Yellowstone yesterday is hospitalized after the snowmobile she was riding left the trail and struck multiple trees at high speed. West Yellowstone Police Department Dispatch received a call from a group of snowmobilers reporting that a member of their party had been involved in a snowmobile crash and had suffered an upper leg injury. Rescuers from Gallatin County Sheriff Search and Rescue in West Yellowstone and Hebgen Basin Fire Department responded to assist with the rescue. Rescuers located the injured girl and her companions using the coordinates retrieved from the 911 call. Her injuries were assessed and she was quickly packaged into a rescue sled and transported back to West Yellowstone to a waiting Hebgen Basin Rural Fire District ambulance. From there, the girl was transported to a hospital by family members. Identity of the victim was not released.
