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.
