| 5. |
| Copy circle 4 three times, to the angular points of triangle 2. |
| 6. |
| Copy circle 1 three times, to the angular points of triangle 2. |
| 7. |
| Construct the inscribed equilateral triangle of circle 4, pointing to the left. |
| 8. |
| Construct the inscribed circle of triangle 7. |
| 9. |
| Construct a circle concentric to circle 1, tangent to circles 5 at the inner sides. |
| 10. |
| Copy circle 9 to the righthand intersection of circle 8 and the horizontal centerline. |
| 11. |
| Construct a circle centered at the upper intersection of circle 8, passing through the upper intersection of circle 10, both with the vertical centerline. |
| 12. |
| Construct a circle concentric to circle 8, tangent to circle 11 at the upper side. |
| 13. |
| Construct a circle concentric to circle 8, tangent to circle 11 at the lower side. |
| 14. |
| Copy circle 11 to the upper intersection of circle 9 and the vertical centerline. |
| 15. |
| Construct a circle concentric to upper circle 5, tangent to circle 14 at the upper side. |
| 16. |

| 20. |
| Copy circle 18 and 19 three times, to the centers of circles 6. |
| 21. |
| Construct a circle centered at the upper intersection and passing through the lower intersection of circle 17 and the vertical centerline. |
| 22. |
| Construct a circle centered at the lower intersection and passing through the upper intersection of circle 17 and the vertical centerline. |
| 23. |
| Construct a circle concentric to circle 1, tangent to circle 21 at the upper side. |
| 24. |
| Construct a circle concentric to circle 1, tangent to circle 22 at the lower side. |
| 25. |
| Circles 5, 12, 13, 16 18, 19, 20, 23 and 24 are used for the final reconstruction. |
| 26. |
| Remove all redundant parts not visible within the formation itself. |
| 27. |
| Colour all areas corresponding to standing... |
| 28. |
| ...or to flattened crop, and finish the reconstruction of the 2009 New Farm formation. |
| 29. |
| The final result, matched with two aerial images. |
