Interesting post
@10ofRods , thank you. I guess there is a degree of complacency in any routine activity (and I don't mean that in a negative way). Out of interest, have you looked at the terrain in the map I linked? The 3D Google Earth version shows all the mountain angles and is surprisingly clear - eg individual trees can be seen. It would seem a fall is the most likely explanation, but it's still strange she's not been found. I must admit, I am definitely not a cold weather person (I need my flip flops!) and while the views are beautiful I am satisfied with seeing someone elses photos of the area; Esther's pics are stunning.
Reading Esther's FB page, it does appear there she needed to spend some time alone:
