Marc Charles Springer was 30 when he disappeared during a climbing trip on Devils Thumb in Southeast Alaska. He and three friends summited the 9,077-foot granite peak on July 23, 2002, and remained on the mountain. His last contact was on July 26, 2002, when he reportedly climbed to a higher elevation to try for cell reception. During that ascent a section of rock is believed to have crumbled, causing a fall of about 50 feet and triggering a large rockslide that buried him.

One climbing partner, Mike Anderson, spent two nights alone near the site where Springer was buried. The Alaska State Troopers concluded that recovery was not feasible without sizable heavy equipment to move the enormous boulders, so a recovery mission did not take place. Marc was remembered by friends and family as an experienced outdoorsman and Powder Mountain Ski Patrol member who found spiritual solace in the mountains.

If anyone was on or near Devils Thumb in late July 2002 or has information about that climb, please share what is known.
