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.
