This photograph she took and that was posted.
I have precisely geolocated it to the spot it was taken at on 21/11. On the link, click it and you will have the direct view behind her, the photo was taken in front of the solar panel and the radio mast, this is visible through her sunglasses on the photo.

Interestingly, all around the area are water features and small lakes.
My theory is, she will have been carrying some weight in her backpack, the terrain is very rocky and shaley too.
My suspicion is she has fell into water somewhere and is weighed down underneath the surface - basing this on the fact she has not been sighted at all anywhere or by anyone after the photo's were taken and sent to her man.
Quite amazed really that she:
A- Actually went and did this on her own, at this time of year in sub zero temperatures on an evening, without any back up or emergency back up.
B- Walking in dark clothes when a hi-viz outfit or something distinct would have been much more sensible.
C- All of my hiking pals and these are super experienced people way above this girls experience, would definitely have not gone out up there solo without being properly equipped for any eventuality. Better still they'd at least have one other hiker with them.
D- She should have been using a GPS tracker linked to another person IE her partner so he can see her location anytime 24/7.
E- She shouldn't have even been out anyway because of lockdown - the French are kicking up a huge stink over this.
F- I smell a rat in their relationship, something isn't adding up, her frame of mind reading some of the posts she has put all over the place sometimes doesn't seem to make sense.
I'd like to know where her campervan was parked up prior to the walk, that was found but it would help to work out her route from the van, to the peak and back -then somewhere within that area is where she'll be found.
