The alternative is almost unthinkable: that George passed camp, then turned left and headed back up the mountain along the North Face. It is far more likely that George summited Everest and came down the Great Couloir, a route he studied with Norton. Note that Messner only needed two hours to descend from the summit through the Great Couloir to a point far lower than where George Mallory’s body was found. If one assumes George was 1/2 as fast as Messner on the descent (note Messner did not use oxygen) then one would estimate it took George about 2 hours to the point where he died from he summit.
On June 8, 1924, Noel Odell spotted his expedition comrades George Leigh Mallory and Andrew Comyn Irvine high on Everest, heading toward fame as the first humans to summit the world’s highest mountain. Then Mallory, the most accomplished British mountaineer of his time, and Irvine, the strong, young novice, simply walked into the mist and into history, never to be seen again.
