More from Brian John about what seems to be the buzzword of the moment - periglacial stipes
Those periglacial stripes are probably not periglacial

Brian writes: What we need here is a detailed topographic survey, but my impression is that these stripes (like the Avenue) point towards the midsummer solstice or sunrise position on the horizon (have I got that right?) but that they do NOT run down the maximum slope inclination towards Stonehenge Bottom. If there is one thing we do know about periglacial stripes it is this: they always run down the maximum inclination of the slope. I have seen a lot of such stripes in my time, in Antarctica, Greenland and Iceland, and I do not recall a single one that was aligned diagonally down a slope.
In the absence of a detailed survey all I can do is speculate about this -- and to say that if these stripes really are periglacial in origin, they should be running from Stonehenge down towards the road junction we can see on the LIDAR image.
Far be it from me to suggest that something perceived as "natural" in origin should now be re-classified as "probably man-made" -- but that is exactly what I am doing!!
[Periglacial stripes have also been recently uncovered near the West Kennet avenue]
