29.		Draw a line from the center of circle 1 to the lower righthand intersection of circles 1 and 10.
30.		Construct a circle centered at the upper intersection of circle 3 and the vertical centerline, passing through the intersection of line 29 and circle 3. (For clarity reasons, the results of some previous steps are temporarily removed).
31.		Copy circle 30 five times, to its clockwise next intersection with circle 3, and consecutively to the corresponding intersections, as shown.
32.		Construct a (non-regular) 6-sided polygon, by connecting the centers of adjacent circles 30 and 31, as shown.
33.		Copy circle 4 six times, to the angular points of polygon 32.
34.		Construct six lines, parallel to the sides of polygon 32 and inside the polygon, pairwise tangent to circles 33, as shown.
35.		Construct a "two-points" circle (defined by the two end-points of a centerline) between the center of circle 4 and its lower intersection with the vertical centerline.
36.		Copy circle 35 four times, to the center of circle 1, and to the upper, the lower lefthand and lower righthand mutual intersections of lines 34, as shown.
37.		Construct three pairs of parallel lines, all tangent to central circle 36 at both sides, and pairwise tangent to the other circles 36 at both sides, as shown.
38.		Copy circle 4 six times, to the mutual intersections of lines 34.
39.		Construct six lines, parallel to lines 34 at the inward sides, pairwise tangent to circles 38, as shown.
40.		Copy circle 4 nine times, to the mutual intersections of lines 37, and to the intersections of lines 37 and 39.
41.		Construct three pairs of lines, parallel to lines 37 at the outward sides, pairwise tangent to circles 40, as shown.
42.		Circles 1, 3, 10, 11, 13, 14, 16, 18, 20, 21, 23, 24, and 27, lines 28, 34, 37, 39, and 41, and polygon 32, are used for the final reconstruction.
43.		Remove all parts not visible within the formation itself. High resolution dwf-file
44.		Colour all areas corresponding to standing... High resolution dwf-file
45.		...or to flattened crop, and finish the reconstruction of the Monument Hill formation of 6-08-2013. High resolution dwf-file
