| 14. |
| Construct a circle concentric to circle 11, tangent to circle 13 at the upper side. |
| 15. |
| Copy circle 14 to the center of circle 10. |
| 16. |

| 17. |
| Copy circle 16 to the upper intersection of circle 1 and the vertical centerline. |

| 19. |
| Construct the circumscribed hexagon of circle 1, pointing up. |
| 20. |
| Construct a "two-points" circle between the lower intersection of circle 1 with the vertical centerline and the top angular point of hexagon 19. |
| 21. |
| Copy circle 1 to its upper intersection with the vertical centerline, and move it to its own corresponding intersection. |
| 22. |
| Copy circle 18 to the center of circle 21. |
| 23. |
| Draw the connecting line between the intersections of circles 18 and 22. |
| 24. |
| Copy circles 3, 6, 9, 10, 11 14 and 15 as a whole, while mirroring with respect to line 23. |
| 25. |
| Copy circle 20, while mirroring with respect to line 23. |
| 26. |
| Construct a circle concentric to circle 1, tangent to circle 25 at the lower side. |
| 27. |
| Copy circle 26 to the center of circle 21. |
| 28. |
| Construct a "two-points" circle between the upper intersections of circles 6 and 21 with the vertical centerline. |
| 29. |
| Construct a "two-points" circle between the upper intersections of circles 9 and 21 with the vertical centerline. |
| 30. |
| Construct a "two-points" circle between the lower intersection of circle 15 and the upper intersection of circle 21, both with the vertical centerline. |
| 31. |
| Copy circles 28, 29 and 30 as a whole, while mirroring with respect to line 23. |
| 32. |
| Circles 1, 3, 6, 9, 10, 11, 14, 15, 18, 20, 21, 22, 24, 25, 26, 27, 28, 29, 30 and 31 are used for the final reconstruction. |
| 33. |
| Remove all redundant parts not visible within the formation itself. |
| 34. |
| Colour all areas corresponding to standing... |
| 35. |
| ...or to flattened crop, and finish the reconstruction of the 2009 East Kennett formation. |
| 36. |
| The final result, matched with two aerial images. |
