| 11. |
| Construct a circle centered at the righthand intersection of circle 6 and the horizontal centerline, tangent to circle 8 at the righthand side. |
| 12. |
| Copy circle 11 to the center of circle 1. |
| 13. |
| Construct a circle centered at the upper intersection of circle 10 and the vertical centerline, tangent to circle 12 at the upper side. |
| 14. |
| Copy circle 13 to the upper intersection of circle 8 and the vertical centerline. |
| 15. |
| Construct a circle concentric to circle 1, tangent to circle 14 at the lower side. |
| 16. |
| Construct a "two-points" circle (defined by the two end-points of a centerline) between the upper intersections of circles 10 and 15 with the vertical centerline. |
| 17. |
| Construct a "two-points" circle between the upper intersections of circles 8 and 15 with the vertical centerline. |
| 18. |

| 21. |
| Construct a circle concentric to circle 1, passing through the center of circle 17. |
| 22. |
| Construct the inscribed octagon (regular 8-sided polygon) of circle 21, pointing up. |
| 23. |
| Copy circles 18 and 20 together seven times, to the other angular points of octagon 22. |
| 24. |
| Draw the connecting line between the center of circle 1 and the upper righthand angular point of square 7. |

| Construct a "two-points" circle between the intersections of circles 10 and 12 with line 24. |
| 26. |
| Construct a circle concentric to circle 1, passing through the center of circle 25. |
| 27. |
| Construct the inscribed square of circle 26, with horizontal and vertical sides. |
| 28. |
| Copy circles 18 and 20 together four times, to the angular points of square 27. |
| 29. |
| Circles 1, 3, 6, 8, 10, 12, 15, 18, 20, 23, and 28, are used for the final reconstruction. |
| 30. |
| Remove all parts not visible within the formation itself. |
| 31. |
| Colour all areas corresponding to standing... |
| 32. |
| ...or to flattened crop, and finish the reconstruction of the 2020 Easton Clump formation. |
| 33. |
| The final result, matched with the aerial image. |
