Another aspect of these 'sacred hills', both artificial, natural and altered natural, is the resemblance of their profile, seen from a distance, to a classic pyramid. It's a tabu subject, of course, but does seem apparent with close observation. I can't think of any that have been 'squared off' and it's generally assumed that the ideal was a limpet-shaped cone. But what if it were actually pyramidical? (Please discuss).
