| |

| 38. | ![]() ![]() ![]()
| |
| Copy circle 31 nr. 1 to the lower righthand intersection of circle 37 and righthand circle 34, and move this circle to its own corresponding intersection. See details. | ||
| 39. | ![]()
| |
| Repeat steps 37 and 38 18 more times for circles 31, nrs. 2, 3, 4, and so on, each time relative to the previously copied circle, as shown. See detail. | ||
| 40. |
| |
| Repeat steps 37 and 38 one more time for circle 30, as shown. | ||
| 41. |
| |

| |

| 43. |
| |
| Remove all redundant parts, not visible in the formation itself. | ||
| 44. |
| |
| Colour all areas corresponding to standing... | ||
| 45. |
| |
| ...or to flattened crop, and complete the reconstruction of the 2008 Below Milk Hill formation. | ||
| 46. | ![]() ![]() |
|
| The final result, matched with aerial images. Since the field runs slightly up in both left and right directions (see tramlines!), and the reconstruction assumes a flat plane, the match can not be done in one time. Upper left: the match, optimized for the righthand "wing" of the formation; lower left: the same for the lefthand "wing"; right: match of the central part with a different aerial image. | ||
