A 17 year old unidentified boy hiking on South Sister apparently fell through a crevasse, injuring himself. The Deschutes County Sheriff’s Office received the distress call from a member of the hiking party around 3 p.m. Tuesday. Search and rescue teams were deployed to the area near the Lewis Glacier where the boy had fallen about 20 feet into the crevasse. He suffered some minor injuries and was able to climb out himself; but authorities transported him by Airlink to a location where they could assess his injuries better. The hiking party consisted of 5 juveniles and two adult chaperones. He was reunited with his family a short time later.
