A very unusual sheathing of straws, where the main circles's rows collected into a standing epicenter far south of the circle's geometrical center. You can just make out its location in the enlarged aerial shot.
Sometimes the straws don't just lie alongside or end with their seed-heads at the formation's boundary, but instead crawl up it in a curving wall.
The beautiful wavy appearance of laid barley is due to the long "whiskers" along its seed-heads, which bunch together in an airy way when the stalks are piled up.
Notice the two standing ridges in 32, which are an intentional part of the lay's pattern in this ring.
Here the waving rows form another clear pattern, beyond barley's natural "airiness".
This nest-center clearly has the dimension of height.
40 was the impressive triple-nested center of the likewise impressive Woodborough Hill formation. 39 is a close-up of the right-hand nest with all its straws bent up in the air. 41 and 42 from the bottommost nest, show a stone the size of a fist, broken into many fitting pieces by either extreme heat or extreme pressure under the circle-creating process - while the surrounding wheat lies undamaged, as usual.
