The largest formation on record: 409 circles spanning some 900 feet across four acres of Milk Hill wheat, found after a night of wind and rain. Six spiral spokes of growing circles each end in a giant, and diminishing chains link the giants into a closed outer rim — 79 major circles dressed with hundreds of satellites.
Major-circle chain digitized from Zef Damen's reconstruction diagram by pixel analysis (six-fold folding, worst residual <1 m). Each arm: 6-circle spoke growing outward (+50°→+12° ahead of the arm's big circle), big circle at 109.4 m from centre, then a 6-circle diminishing rim tail (−12°→−51°) ending tangent to the next arm's big circle, so the 6 bigs + 6 tails close into a rim loop. 55 satellites/arm (notch beads, flankers, two strings) are representative: Zef's survey covers majors only. 6×(13+55)+1 = 409.
