Reconstruction of the 2014 Etchilhampton Hill formation | ||

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

2. |
Construct the inscribed equilateral triangle of circle 1, pointing down. | |

3. |
Construct the inscribed equilateral triangle of circle 1, pointing up. | |

4. |
Draw the connecting line between the righthand angular point of triangle 2 and the lefthand intersection of triangles 2 and 3. | |

5. |
Construct a circle centered at the intersection of the righthand side of triangle 3 and line 4, tangent to the upper side of triangle 2. | |

6. |
Copy circle 5 to the top of triangle 3. | |

7. |
Construct the circumscribed equilateral triangle, pointing down, of the circle concentric to circle 1, and tangent to circle 6 at the upper side. | |

8. |
Construct the circumscribed circle of triangle 7. | |

9. |
Copy circle 5 to the upper intersection of circle 8 and the vertical centerline. | |

10. |
Construct the circumscribed equilateral triangle, pointing down, of the circle concentric to circle 1, and tangent to circle 9 at the upper side. | |

11. |
Construct the circumscribed circle of triangle 10. | |

12. |
Copy circle 5 to the righthand intersection of circle 11 and the horizontal centerline. Move this circle (copy and delete original) to its own corresponding intersection. See detail. | |

13. |
Construct a circle concentric to circle 1, tangent to circle 12 at the righthand side. | |

14. |
Copy circle 5 to the intersection of the righthand side of triangle 10 and the horizontal centerline. | |

15. |
Construct a circle concentric to circle 1, tangent to circle 14 at the righthand side. | |

16. |
Draw three pairs of lines, each pair from a different angular point of triangle 10, to the midpoints of the two nearest sides of triangle 7, as shown. | |

17. |
Draw the connecting line between the righthand angular points of triangles 2 and 3. | |

18. |
Construct a circle centered at the intersection of line 17 and the horizontal centerline, tangent to cirle 1 at the near side. | |

19. |
Copy circle 18 seven times, to the center of circle 1, and to the intersections of circle 15 and lines 16. | |

20. |
Circles 1, 8, 11, 13 and 19, and triangles 2, 7 and 10, make up the final reconstruction. | |

21. |
Colour all areas corresponding to standing... | |

22. |
...or to flattened crop, and finish the reconstruction of the 2014 Etchilhampton Hill formation. | |

23. |
The final result, matched with the aerial image. |
