A 50-year-old man fell off a steep cliff while hiking the Sisters Mountain Saturday. A Coast Guard Air Station Sitka MH-60 Jayhawk helicopter aircrew assisted Alaska State Troopers and Sitka Mountain Rescue personnel to hoist a 50-year-old man after the fall. The man was transferred to Sitka emergency medical services personnel in stable condition but with reported head injuries. Sector Juneau command center watchstanders received notification from Sitka Fire Department personnel at approximately 2 p.m. requesting helicopter support for a man who fell approximately 100 feet while hiking and was reported to have sustained a head and potential back injury from the fall. District 17 command center watchstanders directed the launch of an Air Station Sitka helicopter crew to assist with the rescue. Sitka Mountain Rescue personnel escorted two other hikers in the party off the mountain after the man was safely hoisted.
