Reconstruction of the
Hackpen Hill 30-05-2011 formation

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

2. Construct the inscribed regular 18-sided polygon of circle 1, pointing up.

3. Construct a "two-points" circle (defined by the two end-points of a centerline) between the top and the next angular point to the right of polygon 2.

4. Copy circle 3 to the center of circle 1.

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

6. Construct a circle centered at the top of triangle 5, tangent to circle 4 at the upper side.

7. Copy circle 6 to the lower lefthand angular point of triangle 5.

8. Copy circle 6 to the lower righthand angular point of triangle 5.

9. Copy circle 3 to the righthand intersection of circles 1 and 6 (call this point "A"). Move this circle (copy and delete original) to its own upper lefthand intersection with circle 1.

10. Copy circle 3 to the upper intersection of circles 1 and 7 (call this point "B"). Move this circle to its own lower intersection with circle 1.

11. Construct a circle centered at the upper lefthand intersection of circles 1 and 9, passing through point A.

12. Construct a circle centered at the lower intersection of circles 1 and 10, passing through point B.

13. Construct a "two-points" circle between the lefthand intersections of circles 9 and 11 with circle 1.

14. Draw the connecting line between the centers of circles 1 and 13, and extend this line up to the opposite side of circle 13.

15. Construct a circle centered at the intersection of circle 1 and line 14, passing through point A.

16. Copy circle 15 to point B, and move this circle to its own lower intersection with circle 1.

17. Construct a circle centered at the lefthand intersection of circles 1 and 11, passing through point A.

18. Construct a circle centered at the lower intersection of circles 1 and 12, passing through point B.

19. Construct a circle concentric to circle 6, passing through the intersection of circle 17 and the righthand side of triangle 5.

20. Copy circle 19 to the center of circle 8.

21. Construct a circle centered at the intersection of circle 17 and the righthand side of triangle 5, tangent to circle 6 at the near side.

22. Copy circle 21 to point A.

23. Construct a circle concentric to circle 11, tangent to circle 22 at the lefthand side.

24. Construct a circle concentric to circle 15, tangent to circle 22 at the lefthand side.

25. Construct a circle concentric to circle 17, tangent to circle 22 at the lefthand side.

26. Circles 1, 6, 7, 8, 9, 10, 11, 12, 15, 16, 17, 18, 20, 23, 24 and 25, are used for the final reconstruction.

27. Remove all parts not visible within the formation itself.
