38. "Sixth Sun" crop Formation at Milk Hill
In Whats New item 6, the prediction was made, that 2001 would see the first 13-fold crop formations, since all the other component numbers of the Mayan Long Count had been represented - 20 Kins; 18 Uinals; 20 Tuns; 20 Katuns; only the 13 baktuns were absent.
Actually, Tzolkins and Calendar Round numbers had already appeared:
1997 gave us a 3 x 260 formation = Tzolkins (item 23)
1998 gave us a 13 + 20
formation:

1999 gave us a 18 x 20 formation = aTun; ( Whats New item 6 )
2000 gave us a 20 x 20 formation = Katuns & Baktun ( Whats New item 6 )
In 2001, we didn't get a 13-fold formation, but we did get a "whirling star" with 6 arms, each 13 circles in length. Could this be a representation of 6 "Great Cycles" - we have almost completed the Fifth Sun, and the Sixth Sun starts in 2012. There was a total of 409 circles (- numerologically;4+0+9=13, emphasising 13 again), making it not only the most complex, but also the largest formation to date. Some claimed it appeared on the 13th. A "large star"= a Sun; very apt.
