A party of four was ascending the Fan in Huntington Ravine when one of them fell and slid into two other people in his party causing them to fall as well.  One of three involved in the fall was unable to self arrest on the icy surface and tumbled about 50 feet before hitting a rock.  He sustained a soft tissue injury to his left thigh.  The patient’s party was able to assist him down to the Harvard Cabin and notified the caretaker of the incident and requested assistance.  A Snow Ranger assessed his injuries and transported the patient to Pinkham Notch via snowmobile.
