4. Construct the inscribed pentagon of circle 3, pointing up:

5. Construct the inscribed pentagon of (the inscribed circle of) pentagon 4, pointing down:

6. Construct the inscribed circle of pentagon 5:

7. Draw the diagonal of pentagon 2, from the top to the lower lefthand angular point:

8. Draw the diagonal of pentagon 2, from the top to the lower righthand angular point:

9. Finish the inscribed pentagram of pentagon 2 by drawing the other diagonals:

10. Construct the circumscribed circle of the enclosed pentagon of pentagram 7-8-9:

11. Copy circle 10 to the righthand intersection of circle 1 and the horizontal centerline:

23. Construct a circle concentric to circle 1, tangent to circle 22 at the righthand side:

24. Copy circle 10 to the center of circle 22. Move it to its own righthand intersection with the horizontal centerline:

25. Construct a circle concentric to circle 1, tangent to circle 24 at the righthand side:

26. Only circles 1, 3, 6, 10, 12, 14, 16, 18, 21, 23 and 25 are needed for the final reconstruction:

27. Colour all areas of standing... :

28. ...or of flattened crop, and finish the reconstruction of the Winterbourne Monkton formation of 23-05-2007:
