Some of them also do not exist. They are computer renderings.

The main cc team that made the very complex ones were team satan 666 comprising julian richardson, john lundberg and rob irving. They are extremely good land artists and wrote a book on how to construct them. The majority of the complex ones were real and not cgi as i used to go to wilts and uffington a lot when i was a private hire driver. Very good art and i bought into its not manmade for several years back in the mid 90s. Richardson has moved on to doing similar land art on the sand at Breen in Somerset and sometimes snow art around Avebury. The whole cc industry is or was rife with money making scams even though the so called researchers knew they are manmade and were tipped off in the early morning to get first pictures. The fields around Avebury and Alton Barnes are actually highly visible and some teams have been caught.

They are man made. Below is a documentary from Belgium where they investigate this topic after one poped up on a field. They manage to find a group of students making them. Watch from 20:30. They show the one they requested and then go about making it at night. It is a simple question of geometry using ropes as a giant compas (like the freemason symbol). Then they use planks of different lengths to trample the hay and create the paterns following the giant compas limitations.
It is in french but i will look if i can find the English translation.

Praise the all mighty Zesus. (Not a sun God)

Alone With Everybody (Bukowski)

the flesh covers the bone
and they put a mind
in there and
sometimes a soul,
and the women break
vases against the walls
and the men drink too
much
and nobody finds the
one
but keep
looking
crawling in and out
of beds.
flesh covers
the bone and the
flesh searches
for more than
flesh.

there's no chance
at all:
we are all trapped
by a singular
fate.

nobody ever finds
the one.

the city dumps fill
the junkyards fill
the madhouses fill
the hospitals fill
the graveyards fill

nothing else
fills.

There are other similar cults to freemasonry going on at the same time, we cannot pin everything on the masons though I would love to.
Masons also go by different names like order of the Eastern star, knights templar. Still the same cult.

look at some other ones..

What do you suppose they are up to?
