1. Draw a square, sides horizontally and vertically:

2. Draw another square, pointing up, by connecting the midpoints of adjacent sides of square 1:

3. Construct the inscribed circle of square 2. Draw and extend the horizontal and vertical centerlines:

4. Construct a "two-points" circle (defined by the endpoints of a centerline), by the center of circle 3 and its righthand intersection with the horizontal centerline. Move it (copy and delete original) to its own righthand intersection with the horizontal centerline:

5. Construct a circle concentric to circle 3, tangent to circle 4 at the righthand side:

6. Construct the circumscribed circle of square 1:

7. Construct a circle centered at the upper lefthand angular point of square 1, passing through the diagonally opposite angular point:

8. Construct a circle centered at the upper righthand angular point of square 1, passing through the diagonally opposite angular point:

9. Construct a circle centered at the lower righthand angular point of square 1, passing through the diagonally opposite angular point:

10. Construct a circle centered at the lower lefthand angular point of square 1, passing through the diagonally opposite angular point:

11. Construct a circle concentric to circle 3, passing through the upper righthand intersection of circles 7 and 9:

12. Construct the circumscribed square of circle 11, pointing up:

13. Construct the circumscribed circle of square 12:

14. Construct the circumscribed square of circle 13, sides horizontally and vertically:

15. Construct the circumscribed circle of square 14:

16. Only circles 3, 5, 6, 7, 8, 9, 10 and 15, and square 14 are needed for the final reconstruction:

17. Remove everything not visible in the formation itself:

18. Colour all areas corresponding to standing...:

19. ...or to flattend crop, and finish the reconstruction of the 2007 Wexcombe Down formation:

20. The final result, matched with the aerial image:
