| 4. |
| Construct the inscribed octagon of circle 3, pointing up. |
| 5. |
| Construct the inscribed circle of octagon 4. |
| 6. |
| Construct the inscribed octagon of circle 5, pointing up. |
| 7. |
| Construct the inscribed circle of octagon 6. |
| 8. |
| Construct a circle centered at the top of octagon 6, tangent to the upper sides of octagon 2. |
| 9. |
| Copy circle 8 to its upper intersection with the vertical centerline. |
| 10. |
| Copy circle 9 seven times, to the corresponding positions with respect to the other angular points of octagon 6. |
| 11. |
| Draw the connecting line between the lefthand and righthand intersections (tangent points) of octagon 6 and circle 7, just above the horizontal centerline. |
| 12. |
| Construct a circle concentric to circle 7, tangent to line 11. |
| 13. |
| Construct a circle centered at the lower intersection of circle 8 and the vertical centerline, tangent to circle 12 at the upper side. |
| 14. |
| Copy circle 13 to the center of circle 7. |
| 15. |
| Construct the circumscribed octagon of circle 14, pointing up. |
| 16. |
| Construct the circumscribed circle of octagon 15. |
| 17. |
| Construct a circle centered at the upper intersection of circle 7 and the vertical centerline, tangent to circle 9 at the lower side. |
| 18. |
| Draw the connecting line between two intersections (tangent points) of octagon 6 and circle 7, one at the righthand side just above, the other at the lefthand side just below the horizontal centerline. |
| 19. |
| Copy circle 17 to the upper righthand intersection of circle 16 and line 18. |
| 20. |
| Construct a circle centered at the upper righthand intersection of circle 19 and line 18, passing through the center of circle 17. |
| 21. |
| Construct a circle centered at the lower lefthand intersection of circle 16 and line 18, tangent to circle 14 at the near side. |
| 22. |
| Copy circle 21 to the intersection of circle 20 and line 18. |
| 23. |
| Construct a circle concentric to circle 20, tangent to circle 22 at the lower lefthand side. |
| 24. |
| Construct a circle concentric to circle 7, passing through the upper intersection of circle 23 and the vertical centerline. |
| 25. |
| Construct a circle concentric to circle 7, tangent to circle 19 at the upper righthand side. |
| 26. |
| Construct the inscribed octagon of circle 25, with an angular point coincident with the center of circle 20. |
| 27. |
| Copy circles 20 and 23 together seven times, to the other angular points of octagon 26. |
| 28. |
| Circles 7, 9, 10, 12, 14, 16, 20, 23, 24, and 27, are used for the final reconstruction. |
| 29. |
| Remove all parts not visible within the formation itself. |
| 30. |
| Colour all areas corresponding to standing... |
| 31. |
| ...or to flattened crop, and finish the reconstruction of the 2020 Norton Plantation formation. |
| 32. |
| The final result, matched with the aerial image. |
