I wonder if more bones and/or equipment will eventually be found lower down the scree slope in Cirque de la Glere? If they are, it would suggest a fall. The body could have been hidden amongst the scree/obscured by snow when French LE were searching in Nov/Dec 2020, and some of the bones recently separated and relocated by animals. When the news first broke that bones had been found, I had wondered whether French LE might not have searched the Port de la Glere area as thoroughly, especially given the information DC provided about her probable route. However, the ActuToulouse article ZaZara posted above suggests otherwise - "the area was thoroughly combed by the police during the various search operations on site" and the "bones were not there a few weeks ago".
If more isn't found, it adds further weight to the bearded vulture theory...
I like Otto's thoughts (post 627) about her last messages. Why would you say that you "might dip into France" if that was where you were headed immediately? If she didn't go to the Refuge de Venasque on 22/11, the only feasible way between Pic de Sauvegarde and Port de la Glere would be to descend back to the road on the Spanish side. I wonder if she descended on 22/11, climbed up to Port de la Glere on 23/11, and then intended to possibly walk the Chemin de Imperatrice round to Refuge de Venasque (where she was hoping there might be an open winter room to spend the night of 24/11), crossing back over into Spain at Port de Venasque. It would explain her comments about not being sure whether she'd have signal - she already knew the situation down in the valley on the Spanish side, having stayed at Cabane de Besurtas on 21/11. However, why wasn't she seen? Did anyone stay at the Cabane on 22/11, who could help rule out whether she stayed there again? Did anyone see a lone female walker on the way up to Port de la Glere on 23/11, who perhaps hadn't made the connection that she was ED because she was headed in the 'wrong direction'?
Something struck me today (enough to make me finally register rather than just lurk), about why she might have reversed her route... On the French IGN map (available online at www.geoportail.gouv.fr), the descent into Cirque de la Glere looks steeper and much longer than the one to Refuge de Venasque. She would have seen that the descent from Port de Venasque to Refuge de Venasque was passable on 22/11, on her way up Pic de Sauvegarde. You can't see the Port de la Glere from the summit of Pic de Sauvegarde (it is hidden behind Pic de Montagnette). If she had continued anti-clockwise around the Chemin de Imperatrice, she wouldn't have known until the last minute whether Port de la Glere was passable. However, if she had descended and then walked the route in the opposite direction, starting with Port de la Glere, it removes that uncertainty. She would then know if she could "dip into France", or not. She already knew she could definitely cross back into Spain at the other end...
I agree that it's still possible that the planned hike was from Port de la Glere to the Refuge de Venasque to Port de Venasque (as she stated), or from Port de Venasque to the Refuge to Port de la Glere. If she stayed in Spain overnight after the summit hike and approached France through the Port de la Glere, the question is: how soon would she have noticed the dangerous conditions? Did she hike some distance down the trail, thinking the trail would improve, and then realize she was too far to turn back? Was she unable to turn around and cross the border back into Spain due to slippery steep slope, leaving her no choice but to continue into France?
Thank you for the map link! It's much clearer than most maps. I combined the topo map with your map to see what the terrain looks like at 2200 meters.
