Reconstruction of the
2006 Etchilhampton Hill formation
1. Draw a circle. Draw and extend the horizontal and vertical centerlines.
2. Copy circle 1 four times, to the intersections of circle 1 and the horizontal and vertical centerlines.
3. Copy circle 1 to the righthand intersection of righthand circle 2 and the horizontal centerline. Move this circle (copy and delete original) to its own righthand intersection.
4. Repeat step 3 eight more times, to create (together with righthand circle 2 and circle 3) ten tangent circles on a row, as shown.
5. Repeat steps 3 and 4 relative to the other three circles 2, and in the other three directions, horizontally and vertically. This will yield twenty tangent circles on a row, horizontally as well as vertically, as shown.
6. Construct a circle concentric to circle 1, passing through the intersection of the fourth and fifth circle 4.
7. Draw ten lines, the first from the upper intersection of the first of circles 2 and 5 vertically (up) and the vertical centerline to the righthand intersection of the last circles 2 and 4 (horizontally) and the horizontal centerline, the second from the corresponding intersections of the second of circles 2 and 5 to the second last circles 2 and 4, and so on, as shown.
8. Repeat step 7 three times, for the other three quadrants, as shown.
9. Construct a circle centered at the intersection of the first and last lines 7, tangent to the horizontal centerline.
10. Copy circle 9 three times, to the corresponding intersections in the other three quadrants.
11. Construct a circle centered on the horizontal centerline, passing through the center of the rightmost circle 4, and through its righthand intersection with the horizontal centerline.
12. Repeat step 11 three times, for the three other corresponding circles on the horizontal and vertical centerlines, as shown.
13. Copy circle 11 three times, to the intersections of the first and second, second and third, and third and fourth lines 7.
14. Repeat step 13 for the last four lines 7, as shown.
15. Draw three lines, tangent to circle 11 and successive circles 13, all at the upper sides, as shown.
16. Repeat step 15, for upper circle 12 and successive circles 14, all at the righthand sides.
17. Repeat steps 13 and 14 three times, for the other three quadrants.
18. Repeat steps 15 and 16 three times, for the other three quadrants.
19. Circles 6, 9, 10 11 and 12, lines 7, 8, 15, 16 and 18, and the horizontal and vertical centerlines make up all the required elements for the reconstruction.
20. Remove all parts not visible in the formation itself.
21. Colour all areas corresponding to standing...
22. ...or to flattened crop, which will finish the reconstruction of the 2006 Etchilhampton Hill formation.
23. The final result, matched with the aerial image.
