|
|
31. |
| Circles 1, 3, 6, 13, 17, 19, 20, 28 and 30, and lines 15, are used for the final reconstruction.
|
|
32. |
| Remove all parts not visible within the formation itself.
|
|
33. |
| Colour all areas corresponding to standing...
|
|
34. |
| ...or to flattened crop, and finish the reconstruction of the 2014 Green Street formation.
