I don't think Bob Trubshaw was talking about mountains in Britain - perhaps Tibet, he didn't actually say and talked quite fast.

The book "Sacred Places - Prehistory and Popular Imagination" looks worth reading though - nothing too controversal, chapters titled 'The mythology of places' and 'Experiencing places.' I obviously haven't had time to read it yet but imagine it may be looking at how we superimpose our own values on 'sacred' sites.
