Dead exciting this. See the taller plants in the immediate foreground? There is a curving line of them, heading off to the left of the photo, where they cross the farmer’s track, then they curve backing to the skyline where you can see the little tuft in silhouette. A shape across the photo like a letter C. That, my friends, is the mark on the surface that best reveals the ditch of this mysterious enclosure. This is the NE corner, looking south.
For those who like this sort of thing: this photo was automatically numbered 00666. Smack my ditch up! (It had to be said sooner or later)
