Alaska State Troopers, LifeMed and the Alaska Air National Guard (AKANG) worked together to rescue an injured hiker who fell more than 60 feet on Flattop Mountain early Tuesday morning.

People with the injured hiker, identified as 21-year-old Sterling Horton, called troopers via cellphone shortly after midnight, according an online trooper dispatch. Medical personnel on the ground were able to stabilize him.

LifeMed responded to assist with getting him off the mountain, but the steep terrain prevented them from moving him, a statement from AKANG Sgt. Marisa Lindsay said.

“LifeMed landed their helicopter on top of [Flattop] and provided gear to warm the individual due to him showing signs of hypothermia,” added Tech Sgt. Matt Carse, who works with the Alaska Rescue Coordination Center, in the statement.

Troopers contacted AKANG to send an aircraft capable of hoisting him from where he had fallen. AKANG dispatched a helicopter and crew, who transported Horton to Providence Alaska Medical Center for treatment of his injuries.

“He was released to medical personnel in stable condition,” Lindsay wrote.
