Reconstruction of the
Devil's Den 20-06-2018 formation

1. Draw a circle. Draw and extend the horizontal and vertical centerlines.

2. Construct the inscribed heptagon (regular 7-sided polygon) of circle 1, pointing up.

3. Draw the seven diagonals of heptagon 2 from every angular point to every second angular point, as shown.

4. Construct a circle centered at the top, and passing through the upper righthand angular point of heptagon 2.

5. Copy circle 4 six times, to the other angular points of heptagon 2.

6. Construct a circle centered at the righthand intersection of the horizontal centerline and circle 1, and passing through its intersection with the nearest side of heptagon 2, as shown.

7. Construct a circle concentric to circle 1, tangent to circle 6 at the righthand side.

8. Circles 1, 4, 5, and 7, and lines 3, are used for the final reconstruction.

9. Remove all parts not visible within the formation itself.


10. Colour all areas corresponding to standing...


11. ...or to flattened crop, and finish the reconstruction of the Devil's Den formation of 20-06-2018.
