True, and not arguing that point, but the 4 places I mentioned are on what is now downland and did not have specific hills or mountains. Water I believe was a) the practical reason that settlement slowly took shape, b) and would have figured in the "magical" aspect of these particular landscapes. The rivers, streams, swallet holes on the Mendips, winterbournes in Wiltshire. The Mendips also has (I believe) mesolithic connections in its caves. Westbury quarry (white horse) has bones of a very "early man" discovered some years ago.....
