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. |
