Reconstruction of the 2019 Pepperbox Hill formation | ||

1. |
Draw a circle. Draw and extend the horizontal and vertical centerlines. | |

2. |
Construct the "two-points" circle (defined by the two end-points of a centerline) between the center of circle 1 and its righthand intersection with the horizontal centerline. | |

3. |
Copy circle 2 two times, the first to its righthand intersection with the horizontal centerline, the second to the corresponding intersection of the first. | |

4. |
Copy circle 2 to the righthand intersection of the righthand circle 3 and the horizontal centerline. | |

5. |
Copy circle 2 two more times, the first to the righthand intersection of circle 4 and the horizontal centerline, the second to the corresponding intersection of the first. | |

6. |
Construct a circle concentric to circle 1, tangent to circle 4 at the righthand side. | |

7. |
Construct two circles concentric to circle 1, tangent to circles 5 at the righthand sides. | |

8. |
Copy circle 6 to the center of circle 4, and move this circle (copy and delete original) to its own righthand intersection with the horizontal centerline. | |

9. |
Construct two circles concentric to circle 8, tangent to circles 5 at the righthand sides. | |

10. |
Construct a circle concentric to circle 8, tangent to circle 4 at the righthand side. | |

11. |
Construct two circles concentric to circle 8, passing through the centers of circles 3. | |

12. |
Copy circle 6 to the righthand intersection of circle 10 and the horizontal centerline, and move this circle to its own corresponding intersection. | |

13. |
Construct two circles concentric to circle 12, tangent to circles 11 at the righthand sides. | |

14. |
Construct a circle concentric to circle 12, tangent to circle 10 at the righthand side. | |

15. |
Construct a circle concentric to circle 12, tangent to the outer circle 9 at the righthand side. | |

16. |
Construct a circle concentric to circle 12, tangent to the inner circle 9 at the righthand side. | |

17. |
Construct a "two-points" circle between the righthand intersections of circles 8 and 16 with the horizontal centerline. | |

18. |
Copy circle 17 to the righthand intersection of circle 14 and the horizontal centerline, and move this circle to its own corresponding intersection. | |

19. |
Construct a circle concentric to circle 18, tangent to circle 12 at the righthand side. | |

20. |
Construct two circles concentric to circle 18, tangent to circles 13 at the righthand sides. | |

21. |
Remove all parts from circles 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 18, 19, and 20, such that... | |

22. |
...this pattern remains. | |

23. |
Construct a circle concentric to circle 6 (circle 1), passing through the center of circle 18. | |

24. |
Construct the inscribed hexagon (regular 6-sided polygon) of circle 23, pointing to the right. | |

25. |
Repeat all necessary steps to copy pattern 22 five times, with respect to the other angular points of hexagon 24, while rotating around its center, as shown. | |

26. |
Circle 6, and patterns 22, and 25, are used for the final reconstruction. | |

27. |
Remove all parts not visible within the formation itself. | |

28. |
Colour all areas corresponding to standing... | |

29. |
...or to flattened crop, and finish the reconstruction of the 2019 Pepperbox Hill formation. | |

30. |
The final result, matched with the aerial image. |
