Thanks for that. yeah I was worried the 'red dots of safety" might be a bit off.

I've tried to make the ridge something I've actually crossed where the ridge was crumbling rock to a knife edge instead of sheer cliffs (Somkething I've actually crossed here in NZ carrying a heavy pack; scared the $%#* outta me which I guess is why it made such an impression ). I might have to revisit that idea and see if sheer cliffs are easier to depict
