I haven't been able to follow y'all's X & Y may (or may not) mark the spot on maps discussion, so don't know which if any of the photos linked in this post are where she is thought to have trekked.
FWIW. The first 2 represent a huge difference in degree of difficulty from the 3rd. I spent decades adventuring in the wilderness, including hiking & backpacking above the timberline, and very often alone (though have done very little rope climbing).
Ascending what's in photo 1 & 2 wouldn't constitute a straightforward, family-style hike, but imo, neither would it be exceptionally difficult. More like a challenge but not one risky or reckless.
The 3rd, the snow covered & summit: that's different. No way no how would it have been anything other than risky AND reckless for her to have tried to go that alone, in November, without equipment, her best crampons & a plan she had communicated ahead of time. Was it said by the search team this is where she had gone/tried to go?
These are actually all views of the same peak from different angles, and in different seasons.
The first two pictures are of the Spanish side of the
Pic de la Glère, first from beyond the
Ibon de Gorgutes lake, looking towards the
Port, then from the path on the other side of the lake, taken from a point near the centre of the first picture. They were taken in August.
This picture from the flickr album (
Puerto de la Glera (42)) is the same ridge, looking west to east, so the grassy slopes visible in the first two pictures are on the right of the frame, in Spain. France is on the left. This one (
Puerto de la Glera (44)) is looking back down the path visible in the first two pictures, looking into Spain. All the pictures in that album were taken in late October.
The last picture is looking westwards from the summit proper, back along the summit ridge towards the
Port with the flanks of the
Pic de Sacroux for a backdrop. You can make out the blue waters of the thawing
Ibon de Gorgutes on the left of the picture. The picture was taken in June, before the winter snows had fully melted.
Esther's body was found somewhere on the less accessible French side of this peak. It's been suggested that she may have climbed to a point on the ridge from the Spanish side, then fallen to her death.
Also. Just because her BF said she never did this she always did that when they were hiking together doesn't mean it's odd in the least if she approached things, including hiking, differently when she was alone.
That's very true, and the same thought had occurred to me.
