An Alaska man who was pinned facedown in an icy creek by a 700lb (318kg) boulder for three hours survived the ordeal with only minor injuries, thanks in part to his wife’s quick thinking and lots of luck.

Kell Morris’ wife held his head above water to prevent him from drowning while waiting for rescuers to arrive after Morris was pinned by the boulder, which crashed onto him during a hike near a remote glacier south of Anchorage.

His second stroke of luck came when a sled dog tourism company that operates on the glacier overheard the 911 dispatch and offered up its helicopter to ferry rescuers to the scene, which was inaccessible to all-terrain vehicles.

Once rescuers arrived, it took seven men and inflatable air bags to lift the boulder off as he drifted in and out of consciousness.

Morris, 61, said he realizes he is probably the luckiest man alive. “And luckier that I have such a great wife,” he said Thursday.
