A mountaineer was injured while descending the Lobster Claw in Tuckerman Ravine. During the descent, he lost his footing and took a tumbling fall down the gully injuring his hip. Snow Rangers and a member of the Mt. Washington Volunteer Ski Patrol assessed his injuries and assisted him down to Hermit Lake where he was transported to Pinkham Notch in the USFS snowcat. This incident involved four rescuers and took three hours to complete.
