Hannelore's not sitting there any longer. After spending a quarter century as a waypoint marker for Southern route Everest climbers, her body was finally blown off the face by a storm, perhaps a decade ago. I believe the same storm blew 'Green Boots' off the mountain as well. Green Boots was the Indian climber who died right at the face of the little cave close to the summit. The cave (really an overhang) is described in almost any Everest literature - climbers often seek refuge there. Green Boots was a waypoint marker for a decade or so.
As a result of the storm, Hannelore is gone and nobody ever claimed the $100,000 reward her husband offered to anyone who would bring down the body - that was considered by climbers to be suicide. The Sherpa and Nepalese police officer who attempted to do so in 1984 died.
