| 9. |
| Construct two inscribed equilateral triangles of circle 8, one pointing up, one pointing down. |
| 10. |
| Construct the inscribed circle of the hexagon enclosed by triangles 9. |
| 11. |
| Construct a circle (concentric to circle 1) passing through the mutual intersections of triangles 7. |
| 12. |
| Copy circle 11 to the top of hexagon 2, and move this circle (copy and delete original) to its own lower intersection with the vertical centerline. |
| 13. |
| Copy circle 11 two times, to the corresponding positions on rays 3 nrs. 3 and 5. |
| 14. |
| Construct a circle centered at the intersection of circle 4 and ray 3 nr. 2, passing through the righthand intersection of circle 4 and the upper horizontal side of triangles 5. |
| 15. |
| Copy circle 14 to the intersection of circle 10 and ray 3 nr. 2. |
| 16. |
| Construct a circle concentric to circle 1, tangent to circle 15 at the upper righthand side. |
| 17. |
| Copy circle 16 to the top of hexagon 2, and move this circle to its own lower intersection with the vertical centerline. |
| 18. |
| Copy circle 16 five times, to the corresponding positions on the other rays 3 (nrs. 2, 3, 4, 5, and 6). |
| 19. |
| Construct a circle passing through the top of hexagon 2, and passing through the upper two intersections of circle 16 and triangles 9. |
| 20. |
| Copy circle 19 two times, to the corresponding positions on rays 3 nrs. 3 and 5. |
| 21. |
| Construct a circle concentric to circle 19, tangent to circle 8 at the upper side. |
| 22. |
| Copy circle 21 two times, to the centers of circles 20. |
| 23. |
| Construct a circle centered at the lower lefthand intersection of circle 14 and ray 3 nr. 2, passing through the other intersection. |
| 24. |
| Copy circle 23 to the center of circle 1. |
| 25. |
| Construct a circle centered at the intersection of the righthand side of hexagon 2 and the horizontal centerline, tangent to the nearest sides of triangles 5. |
| 26. |
| Construct a circle concentric to circle 1, tangent to circle 25 at the righthand side. |
| 27. |
| Construct a "two-points" circle (defined by the two end-points of a centerline) between the lower intersections of circles 10 and 24 with the vertical centerline. |
| 28. |
| Copy circle 27 two times, to the centers of circle 1 and the lower circle 18. |
| 29. |
| Construct two lines, parallel to ray 3 nr. 4, tangent to circles 28 at both sides. |
| 30. |
| Repeat steps 28 and 29 two times, with respect to rays 3 nrs. 2 and 6. |
| 31. |
| Circles 1, 10, 12, 13, 16, 17, 18, 19, 20, 21, 22, 24, and 26, and lines 29 and 30, are used for the final reconstruction. |
| 32. |
| Remove all parts not visible within the formation itself. |
| 33. |
| Colour all areas corresponding to standing... |
| 34. |
| ...or to flattened crop, and finish the reconstruction of the 2019 Stanton St. Bernard formation. |
| 35. |
| The final result, matched with the aerial image. |
