| 1. |
| Draw a circle. Draw and extend 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. |
| Construct a circle centered at angular point nr. 1, passing through angular point nr. 2. |
| 4. |
| Construct a circle centered at angular point nr. 2, passing through angular point nr. 1. |
| 5. |
| Construct a circle centered at angular point nr. 12, passing through angular point nr. 1. |
| 6. |
| Draw the connecting line between the center of circle 1 and the upper intersection of circles 3 and 4. |
| 7. |
| Construct a circle centered at the intersection of dodecagon 2 and line 6, tangent to circle 5 at the righthand side. |
| 8. |
| Copy circle 7 to the center of circle 1. |
| 9. |
| Construct a circle centered at the lower intersection of circles 4 and 5, tangent to line 6. |
| 10. |
| Copy circle 9 to the center of circle 1. |
| 11. |
| Construct a circle centered at the lower intersection of circle 3 and the vertical centerline, tangent to line 6. |
| 12. |
| Copy circle 11 to the center of circle 1. |
| 13. |
| Construct a circle passing through angular points nrs. 1 and 6, tangent to circle 10 at the lefthand side. |
| 14. |
| Construct a circle passing through angular points nrs. 2 and 7, tangent to circle 10 at the lefthand side. |
| 15. |
| Construct a circle concentric to circle 14, tangent to circle 8 at the lefthand side. |
| 16. |
| Construct a circle centered at the upper intersection of circles 8 and 14, tangent to circle 15 at the near side. |
| 17. |
| Remove all parts from circles 4, 8, 13, 15, and 16, such that the shown pattern remains. |
|
| ||
| 18. |
| Copy pattern 17 eleven times, to the corresponding positions with respect to the other angular points of dodecagon 2, as shown. |
| 19. |
| Copy circle 9 to the center of circle 7. |
| 20. |
| Copy circle 11 to the center of circle 7. |
| 21. |
| Construct a circle concentric to circle 1, tangent to circle 7 at the upper side. |
| 22. |
| Construct a circle concentric to circle 1, tangent to circle 19 at the upper side. |
| 23. |
| Construct a circle concentric to circle 1, tangent to circle 20 at the upper side. |
| 24. |
| Circles 10, 12, 21, 22, and 23, and patterns 17 and 18, together, make up the final reconstruction. |
| 25. |
| Colour all areas corresponding to standing... |
| 26. |
| ...or to flattened crop, and finish the reconstruction of the 2018 Clifford's Hill formation. |
| 27. |
| The final result, matched with the aerial image. |
