Reconstruction of the
2001 Woodborough Hill (2) formation

1. Draw a circle.

2. Draw the horizontal and vertical centerlines.

3. Construct the circumscribed equilateral triangle of circle 1, pointing downwards.

4a. Construct the circumscribed nonagon (regular 9-sided polygon) of equilateral triangle 3, such that angular points of both coincide, as shown.

4b. Construct the other two equilateral triangles, inscribed in nonagon 4a, the angular points of which coincide also with those of the nonagon, as shown.

5. Draw the nine rays of nonagon 4a.

6. Draw the diagonals of nonagon 4a, connecting every second angular point.

7. From the intersections of rays 5 and diagonals 6 of nonagon 4a (forming another nonagon in itself), draw the corresponding diagonals, parallel to diagonals 6.

8. Construct a circle concentric with circle 1, passing through the intersections of diagonals 7 and sides of equilateral triangles 3 and 4b, as shown.

9. Construct the circumscribed hexagon (regular 6-sided polygon) of circle 1.

10. Construct the circumscribed circle of hexagon 9.

11. Extend rays numbered "3" and "5" (counterclockwise from the horizontal centerline on the right), until they meet circle 8 at the opposite side, as shown.

12. Draw a line connecting the end-points of the extended rays and a line connecting the end-points of the two rays, mirrored in relation to the horizontal centerline, as shown.

13. Construct a circle concentric to circle 1, passing through the intersection of lines 12, as shown.

14. Construct the inscribed equilateral triangle of circle 8, pointing down.

15. Construct a circle concentric to circle 1, passing through the intersections of the sides of triangle 14 and rays 5.

16. Draw the connecting line between the intersections of rays "3" and "7" (see step 11) and circle 13, as shown.

17. Construct a circle concentric to circle 1, tangent to line 16.

18. Construct the inscribed nonagon of circle 1, pointing up.

19. Draw the connecting line between the lower intersection of circle 1 and the vertical centerline, and the intersection of nonagon 18 and ray "2", as shown.

20. Construct a circle concentric to circle 1, tangent to line 19.

21. Copy circle 8 two times, one each to the intersections of circle 1 with rays "1" and "6", as shown.

22. Construct a circle concentric to circle 1, passing through the intersection of circles 21 closest to circle 1, as shown.

23. Copy circle 8 another time to the intersection of circle 22 and ray "8". Copy circle 10 to the intersection of circle 22 and ray "7", as shown.

24. Clip off the parts of circles 23 outside circle 1 up to their mutual intersection inside circle 1, as shown.

25. Copy circle 20 to the intersection of (the remainder of) copied circle 8 (step 23) and circle 15, as shown.

26. Copy circle 20 another time to the upper left intersection of circle 25 and circle 15, as shown.

27. Repeat steps 23 through 26 for all other pairs of (consecutive) rays, nine times in total.

28. Circles 1, 8, 10, 13, 17, 20, 24, 26 and 27 together form all the parts for the reconstruction.

29. Removing all elements not present in the final formation and making black relevant parts denoting standing crop, finishes the reconstruction of the 2001 Woodborough Hill (2) formation.
