Reconstruction of the 2016 Mount Pleasant formation | ||

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

2. |
Construct the inscribed dodecagon (regular 12-sided polygon) of circle 1, pointing up. Number the angular points clockwise 1 - 12, starting at the top. | |

3. |
Draw the line 2-12 (between angular points 2 nrs. 2 and 12). | |

4. |
Construct a circle concentric to circle 1, tangent to line 3. | |

5. |
Construct the inscribed dodecagon of circle 4, pointing up. Number the angular points clockwise 13 - 24, starting at the top. | |

6. |
Draw six lines: 1-23 (between angular point 2 nr. 1 and angular point 5 nr. 23), 3-13, 5-15, 7-17, 9-19, and 11-21. | |

7. |
Construct the inscribed hexagon (regular 6-sided polygon) of circle 4, pointing to the right. | |

8. |
Draw a line from angular point 13 to the intersection of line 1-23 and the upper lefthand side of hexagon 7. Repeat this five times, for the angular points 15, 17, 19, 21, and 23, to the other corresponding intersections, as shown. | |

9. |
Draw six lines: 2-23, 4-13, 6-15, 8-17, 10-19, and 12-21. | |

10. |
Draw six lines: 2-18, 4-20, 6-22, 8-24, 10-14, and 12-16. | |

11. |
Construct a circle centered at the intersection of the leftmost line 8 and the horizontal centerline, passing through the intersection of lines 11-21 and 6-22. See detail. | |

12. |
Copy circle 11 two times, to angular points 4 and 13. | |

13. |
Construct a line parallel to line 4-13, tangent to circles 12 at the lower lefthand sides. Extend this line up to the closest line 8. See detail. | |

14. |
Repeat steps 12 and 13 five times, for the other corresponding pairs of angular points, as shown. | |

15. |
Copy circle 11 two times, to angular points 2 and 18. | |

16. |
Construct a line parallel to line 2-18, tangent to circles 15 at the lefthand sides. | |

17. |
Repeat steps 15 and 16 five times, for the other corresponding pairs of angular points, as shown. | |

18. |
Circle 1, and lines 6, 8, 9, 10, 13, 14, 16, and 17, are used for the final reconstruction. | |

19. |
Remove all parts not visible within the formation itself. | |

20. |
Colour all areas corresponding to standing... | |

21. |
...or to flattened crop, and finish the reconstruction of the 2016 Mount Pleasant formation. | |

22. |
The final result, matched with the aerial image. |
