John McKimm Millar, 24, went missing while attempting the north face of Devil’s Thumb in Alaska with partner Guy Edwards on April 13, 2003. Millar and Edwards left from a glacier camp after skiing in for three days; a third climber, Kai M. Hirvonen, did not join the ascent and last saw their headlamps faintly at night before they disappeared into the mountain.

The pair carried gear and food for a four to five-day climb. Weather in the days after their departure was mostly poor, pilots reported recent avalanches near the route, and searches by helicopter and fixed-wing aircraft were repeatedly hampered by low clouds and worsening conditions. After nearly a week with no sign of the climbers, Alaska State Troopers called off the official search.

Millar and Edwards are presumed deceased, lost on the Devil’s Thumb. If anyone was on the mountain at that time or has information about the climb or its last-known location, please share what is known.
