I wonder if anyone has investigated whether at the other end, close to The Sanctuary, the route of the Avenue equates with the easiest route down the slope?
That would be the single most useful study in my eyes. If that were true then everything is blown out. It just goes from A-B the easy way.Anything that snakes can have tangents drawn to provide alignments. What is needed is horizon features. The presence of a barrow mentioned above as possibly fortuitous is a prime example. The avenue could align on it or it could have been built there to align with the avenue at a later date. If the barrow came first then the solar/lunar alignment is either significant or just a really nice effect to be seen from the avenue.
It's all fascinating stuff!
