We know that she was alive and well in Spain on Nov 22 at 3PM ascending the mountain, and that she sent a photo from the summit at 4PM. According to her partner, the trip plan was to climb the Pic de Sauvegarde, then overnight at the Refuge de Venasque. There is no evidence that she arrived at the Refuge.
Authorities, early in the search, stated that she began her hike on Nov 22 and planned to return on Nov 25. When she did not contact her partner on Nov 25, he reported her missing.
If we doubt that she started the hike on Nov 22, doubt that she used the summit wifi signal to send the photo at 4PM, doubt that she was responsible enough to stick to the trip plan, then of course, we know nothing.
I'm just providing some snippets from news reports in first weeks of December and have highlighted a few key points:
1. Extent of police search is 28sq km - using drone/ helicopter / on foot

Captain Bordinaro said police, having searched 28sq km of mountains since she was reported missing by Mr Colegate, 38, on November 24, do not believe that Esther had an accident and is in the Pyrenees.
‘Her disappearance is more likely to be the result of a voluntary or criminal act.
‘We have carried out a very thorough search of the area in the French sector. We have covered 28 square kilometres by foot, drone and helicopter and there is no trace of her.
‘We are cooperating thoroughly with the Guardia Civil [Spanish paramilitary police] who have also carried out a thorough search of their sector.
Point 2: It's odd that the poice searched for the 'fellow hiker' but then there was no follow up report. We know they did locate him - but there was never a statement to the effect of ' we are happy that the man in question is not a suspect' ..
It was revealed on Wednesday night that investigators are seeking a man who gave the solo hiker a lift and Spanish and French authorities believe he could prove crucial in tracking her down.
Esther shared the existence of the man in a Facebook post on November 19, saying they met by chance at the peak of a mountain, before hiking down together.
She said she had accepted a lift from the man back to her camper van, which was later found abandoned in the Spanish town of Benasque.
'They may have arranged to meet and hike another route. It is imperative that we find him.'
But the force has remained tight-lipped about the work they are doing.
They have privately dismissed the idea the hiker could have been attacked by a bear and have made no comment on reports they are hunting a man travel blogger Esther said in her online travel diary had given her a lift down from the mountains in the days before she vanished.
Point 3: She was headed towards Pico Salvaguardia on 19th.... and climbed it on 21st Nov (and possibly 22nd) ... so a long time in this area
Police have spoken to hikers who saw Esther, who rowed for Great Britain as a schoolgirl, heading towards Pico Salvaguardia on November 19.
Well-placed sources confirmed she had been on Pic de Sauvegarde on the Spanish side of the border on November 21 and posted a selfie on Instagram before returning the following day.
Esther Dingley: Police believe missing British hiker went missing voluntarily | Daily Mail Online
Speaking exclusively to the Mail this week, Jose Antonio Ballarin - who gave Ms Dingley a lift on October 21 - said Esther discussed her route with him, and it was different from the one she was believed to have been planning.
Under
Spain's
lockdown rules, the retired businessman shouldn't have offered a lift to a stranger at all. But something about the sight of the 37-year-old woman carrying a large khaki backpack made him pull over, he said.
Esther, who often took lifts on hiking trips, jumped in and travelled with the 71-year-old and his grandson for five miles, chatting about her plans until they reached the footpath leading to the Pico Salvaguardia, or 'safeguard peak'.
When she went missing, she was thought to have been in the middle of a hike of several days, taking a circular route from Port de la Glere to Port de Venasque via Pico Salvaguardia.
