2019 Pepperbox Hill formation
|
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. |
