Good knowledge. And yet one of the primary defences about her disappearance at the beginning was the great weather. I think, based on the authorities not wanting to risk staff at high altitudes in winter's variable conditions, I'd be very wary of walking in the Pyrenees in winter. I mean, I personally wouldn't anyway but committed hikers may need to consider the possibility that if something goes wrong they could be alone. For days. Perhaps weeks. Summer, and the local policies due to topography in that area might not present such a problem. I do worry that she may have died alone and in pain and away from people. I really hope those endorphins made her drift off comfortably. Perhaps it's what she wanted. I guess we'll never know. I was haunted by her "I could stay here forever" message too.
