The victim was hiking out of the Tuckerman Bowl at approximately 2:15pm carrying his snowboard. About half way down the trail to Hermit Lake he slipped on some ice, tumbled two or three times and fell along his snowboard. The edge of the board cut through his clothing and put an eight inch long laceration on his outer right thigh. The board cut through muscle and hit his femur. Forest Service Snow Rangers were contacted and responded to the scene. The bleeding was controlled and the victim was put in a litter and taken to Hermit Lake. From there he was transported by snowcat to an ambulance waiting at Pinkham Notch. At the hospital the victim received hundreds of stitches and will require physical therapy to recover. This accident took 6 people two hours to complete.
