Rather like the story?
That Scottish mountain story is an infuriating mishmash of the same old script (she uses exactly the same expression for the mountain, 'a tsunami of rock', in TWS, ditto Moth 'pushing his huge size twelve feet' against the tentpole) and her usual 'getting her own details slightly wrong' compared to the published text she's rehashing.
She says in that interview that her parents thought she was 'going somewhere else', but in TWS they knew where she was going, to the north of Scotland, but thought it was with TW's entire family.
She uses the name of the mountain repeatedly in TWS, but I bet she didn't know how to pronounce it and couldn't be bothered to look it up.
And that guff about the 'voice of the mountain' calling them and then turning out to be deer calling to one another? Red deer don't make any noise that could be described as 'singing'. The males roar in rutting season, and the females sort of miaow to their newborn fawns in spring, but none of that sounds at all like 'singing' or anything as mystical as SW's description, in which they're being drawn hypnotically towards the mountain, which she'd also dreamed about on the train to Scotland.
In fact, stripped of the purple prose, this was an unusually immature and sheltered sex-drunk 20 year old going on holiday, with subpar borrowed equipment, with a first boyfriend who is not that nice to her, making her climb mountains with a fully-loaded, ill-fitting rucksack, and apparently unconcerned that her shoulders are welted and bloody, attracting the sympathy of the entire campsite, that she doesn't want to go to this particular mountain, or that he almost got her killed when they did.
