It's bizarre (though I suppose we knew it would be). Having scoured Google Earth, the only places where she could have fallen to her death without being easily spotted are well off the path and hardly places she (or anyone) would want to get to, especially in that season. It's surely technically possible to get up to the ridge to the east of P de la Glere, or even to the top of that small pic, but it would be quite a scramble and the view from the top would hardly be worth it (not much better than from P de la Glere itself and nothing like as good as from Sauvegarde).
I'm assuming she was found on the French side, though as usual it's the drip-drip of information that is liable to get distorted along the way. They could easily describe exactly where she was found or even pin-point it on a map, but it's always a case of 'betray the information, lose the power'. As was definitely the case with Libby Squire in Hull, the authorities are desperate not to let the public crack the case before they do. It's possible we may never get to know the exact spot where Esther fell/was found.
In the meantime, given the oddness of the likely location, suicide still has to be a possibility.
