Adam Ibbotson and @WC21UKProductionsLtd published a Youtube video today - below - in which they notice an unrecorded henge like shape. Of course I had to find it using the Lidar Lens, link above. Intriguing. Watch the video for more:
Adam comments:
More like “stumbled upon” / rediscovered 😅 As mentioned, Mr Phil Barrett emailed me a screenshot of one of them 4 or 5 years ago. He found they were already recorded.
Recorded or not I don't see a henge there. LiDAR can play all sorts of tricks without some experience comparing imagery with field inspection. But you can to a certain extent on Google Earth with this site. Go to the historical aerial for September 2011. It's quite an obvious feature. View it vertically, obliquely and generate elevation transects, and you might conclude differently too. IMO largely natural.
