One scenario several of us considered long ago (e.g. Thread #2 or 3 perhaps) was whether ED went to Maladeta Glacier, which sits west of both Ports de V and G. The base of the glacier is accessible by a trail near the Cabane de la Besurta. Given the location of where ED died is still a mystery, I thought I'd resurrect this scenario as it may fit.
From her own FB words, ED considered glaciers "mystical". She was therefore likely attracted to them, with fascination.
What if, as many here speculate, ED descended from pic de S and returned to Cabane de la Besurta, the evening of 22/11. And rather than immediately heading along a clockwise trek to Port de la Glere, ED decided to poke around Maladeta Glacier, the base of which is very near the Cabane. Or maybe she always intended to go to Maladeta and kept that quiet.
If she did go to Maladeta Glacier, perhaps she had a fatal or near-fatal accident (then died). It is a very rocky steep.
But also, perhaps as some of us may still ponder, ED could have committed suicide in her mystical setting. Not sure how many others think this way at this point, but I do believe there remains a 50% chance ED was focused on ending her life.
