Crop circles are patterns created by flattened crops such as wheat or barley. While some early historical accounts exist, reports of crop circles increased substantially from the 1970s onward. The majority have been located in southern England near ancient sites like Stonehenge. Though the exact means of formation is unknown, explanations range from hoaxes created by people to weather or paranormal phenomena. Debate continues on whether all can be explained as human creations or if some might have other causes.

A crop circle is a sizable pattern created by the flattening of a crop such as wheat, barley, rye,
maize, or rapeseed. Crop circles are also referred to as crop formations, because they are not
always circular in shape. While the exact date crop circles began to appear is unknown, the
documented cases have substantially increased from the 1970s to current times. Twenty-six
countries reported approximately ten thousand crop circles in the last third of the 20th century.
Ninety percent of those were located in southern England.[1] Many of the formations appearing in
that area are positioned near ancient monuments, such as Stonehenge. According to one study,
nearly half of all circles found in the UK in 2003 were located within a 15 km (9.3 miles) radius
of Avebury.[2]

[edit] History
1678 pamphlet on the "Mowing-Devil".
The earliest recorded image resembling a crop circle is depicted in a 17th century English
woodcut called the Mowing-Devil. The image depicts the Devil with a scythe mowing (cutting)[3]
a circular design in a field of oats. The pamphlet containing the image states that the farmer,
disgusted at the wage his mower was demanding for his work, insisted that he would rather have
"the devil himself" perform the task.
A historical report of crop circles, republished (from Nature, 1880)[4][5] in January 2000 Journal
of Meteorology[6] describes the 1880 investigations by amateur scientist John Rand Capron:
The storms about this part of Surrey have been lately local and violent, and the
effects produced in some instances curious. Visiting a neighbour's farm on
Wednesday evening (21st), we found a field of standing wheat considerably
knocked about, not as an entirety, but in patches forming, as viewed from a
distance, circular spots....I could not trace locally any circumstances accounting
for the peculiar forms of the patches in the field, nor indicating whether it was
wind or rain, or both combined, which had caused them, beyond the general
evidence everywhere of heavy rainfall. They were suggestive to me of some
cyclonic wind action ...[7]
Most historical accounts of crop circles are anecdotal, in some cases describing crops being cut
or burnt rather than flattened.[8][9][10] One report given in 1966 from the town of Tully,
Queensland, Australia, came from a sugar cane farmer who said he witnessed a saucer-shaped
craft rise 30 or 40 feet (12 m) up from a swamp and then fly away. When he went to investigate
the location where he thought the saucer had landed, he found the reeds intricately woven in a

3. clockwise fashion on top of the water. Reportedly, the woven reeds are said to have been able to
hold the weight of 10 men.[11][12]
Public attention to crop circles rose in the late 1970s as many circles began appearing throughout
the English countryside. This phenomenon became widely known in the late 1980s, after the
media started to report crop circles in Hampshire and Wiltshire. To date, approximately 10,000
crop circles have been reported internationally, from locations such as the former Soviet Union,
the UK, Japan, the U.S. and Canada. Skeptics note a correlation between crop circles, recent
media coverage, and the absence of fencing and/or anti-trespassing legislation.[13]
Although farmers have expressed concern at the damage caused to their crops, local response to
the appearance of crop circles can be enthusiastic, with locals taking advantage of the increase of
tourism and visits from scientists, crop circle researchers, and individuals seeking spiritual
experiences.[14] The market for crop-circle interest has consequently generated bus or helicopter
tours of circle sites, walking tours, T-shirts and book sales.
The last decade has witnessed crop formations with increased size and complexity of form, some
featuring as many as 2000 different shapes,[15] and some incorporating complex mathematical
and scientific characteristics.[16][17][18]
[edit] Bower and Chorley
In 1991, self-professed pranksters Doug Bower and Dave Chorley made headlines claiming it
was they who started the phenomenon in 1978 with the use of simple tools consisting of a plank
of wood, rope, and a baseball cap fitted with a loop of wire to help them walk in a straight line.
Inspired by Australian crop circle accounts from 1966, Doug and Dave reportedly made more
than 200 crop circles from 1978–1991 and claimed to be responsible for most if not all circles
made prior to 1987.[19][20][21] After their announcement, the two men demonstrated making a crop
circle.[22] Despite general acceptance of their story, crop circle researchers remain skeptical of
many of their claims.[21][23][20] Since their revelation, crop formations have continued to appear
each year, often in greater number, size, and complexity.
[edit] Art and business
Since the early 1990s the UK arts collective founded by artists Rod Dickinson and John
Lundberg (and subsequently includes artists Wil Russell and Rob Irving), named the
Circlemakers, have been creating some crop circles in the UK and around the world both as part
of their art practice and for commercial clients.[24][25]
On the night of July 11–12, 1992, a crop-circle making competition, for a prize of several
thousand UK pounds (partly funded by the Arthur Koestler Foundation), was held in Berkshire.
The winning entry was produced by three Westland Helicopters engineers, using rope, PVC pipe,
a trestle and a ladder. Another competitor used a small garden roller, a plank and some rope.
In 2002, Discovery Channel commissioned five aeronautics and astronautics graduate students
from MIT to create crop circles of their own, aiming to duplicate some of the features claimed to

4. distinguish "real" crop circles from the known fakes such as those created by Bower and
Chorley. The creation of the circle was recorded and used in the Discovery Channel
documentary Crop Circles: Mysteries in the Fields.[26]
[edit] Legal implications
In 1992 Hungarian youths Gábor Takács and Róbert Dallos, both then 17, were the first people
to face legal action after creating a crop circle. Takács and Dallos, of the St. Stephen Agricultural
Technicum, a high school in Hungary specializing in agriculture, created a 36-metre (118 ft)
diameter crop circle in a wheat field near Székesfehérvár, 43 miles (69 km) southwest of
Budapest, on June 8, 1992. On September 3, the pair appeared on Hungarian TV and exposed the
circle as a hoax, showing photos of the field before and after the circle was made. As a result,
Aranykalász Co., the owners of the land, sued the youngsters for 630,000 Ft (approximately
US$3,000) in damages. The presiding judge ruled that the students were only responsible for the
damage caused in the circle itself, amounting to about 6,000 Ft (approximately US$30), and that
99% of the damage to the crops was caused by the thousands of visitors who flocked to
Székesfehérvár following the media's promotion of the circle. The fine was eventually paid by
the TV show, as were the students' legal fees.[citation needed]
In 2000, Matthew Williams became the first man in the UK to be arrested for causing criminal
damage after making a crop circle near Devizes.[27]
[edit] Explanations
Formations usually are made overnight, but have also been made during the day. While it is not
known how all crop circles are formed, various theories have been put forth ranging from natural
phenomenon and man-made hoaxes, to the paranormal and even animals.[28][29][30][31]
[edit] Man-made
The most widely known method for a person or group to construct a crop formation is to tie one
end of a rope to an anchor point, and the other end to a board which is used to crush the plants.
Some crop formations are paid for by companies who use them as advertising.[32] As an
explanation of some of the more complex formations, physicists have suggested the use of GPS,
lasers, and portable microwave generators.[33][34]
[edit] Weather
Some have suggested crop circles are the result of extraordinary meteorological phenomena
ranging from freak tornadoes to ball lightning.[35] The first known published reference to the
possibility of crop formations being the result of natural phenomena dates back to 1880 in which
investigator and amateur scientist John Rand Capron theorized the formations may have been the
product of "cyclonic wind action..." [6][7] Physicist Stephen Hawking expressed the opinion in
1992 that, "Corn circles are either hoaxes or formed by vortex movement of air".[7][36]

5. [edit] Paranormal
Sketch of a 'spaceship' creating crop circles, sent to UK Ministry of Defence circa 1998.
Since appearing in the media in the 1970s, crop circles have become the subject of speculation
by various paranormal, ufological, and anomalistic investigators ranging from proposals that
they were created by bizarre meteorological phenomena to messages from extraterrestrial
beings.[35][37][38][39]
Many crop circles have been found near ancient sites such as Stonehenge, a prehistoric
monument located in the English county of Wiltshire. They have also been found near mounds of
earth and stones raised over a grave or graves, also known as tumuli barrows, or barrows and
chalk horses, or trenches dug and filled with rubble made from brighter material than the natural
bedrock, often chalk. There has also been speculation that crop circles have a relation to ley
lines.[37][40][41] Many New Age groups incorporate crop circles into their belief systems.
Some have related crop circles to the Gaia hypothesis, alleging that "Gaia", the earth, is actually
alive and that crop circles are messages or responses to stimuli such as global warming and
human pollution. It asserts that the earth may be modeled as if a single super-organism, in that
earthly components (e.g. biota, climate, temperature, sunlight, etc.) influence each other and are
organized to function and develop as a whole.[42]
The main criticism of alleged non-human creation of crop circles is that while evidence of these
origins, besides eyewitness testimonies, is essentially absent, some are definitely known to be the
work of human pranksters and others can be adequately explained as such. There have been
cases in which researchers declared crop circles to be "the real thing", only to be confronted with
the people who created the circle and documented the fraud.[43] In his 1997 book The Demon-
Haunted World: Science as a Candle in the Dark, Carl Sagan discussed alien-based theories of
crop circle formation. Sagan concluded that no empirical evidence existed to link UFOs with
crop circles.[44] Many others have demonstrated how complex crop circles can be created.[32][45]
Scientific American published an article by Matt Ridley,[19] who started making crop circles in
northern England in 1991. He wrote about how easy it is to develop techniques using simple
tools that can easily fool later observers. He reported on "expert" sources such as the Wall Street
Journal who had been easily fooled and mused about why people want to believe supernatural
explanations for phenomena that are not yet explained. Methods of creating a crop circle are now
well documented on the Internet.[32]

6. Among others, paranormal enthusiasts, ufologists, and anomalistic investigators have offered
hypothetical explanations that have been criticized as pseudoscientific by skeptical groups like
the Committee for Skeptical Inquiry.[46][47][48][49]
Responding to local beliefs that "extraterrestrial beings" in UFOs were responsible for crop
circles appearing in Indonesia, the government and the National Aeronautics and Space Agency
(Lapan) described them as "man-made". Thomas Djamaluddin, research professor of astronomy
and astrophysics at Lapan stated: "We have come to agree that this 'thing' cannot be scientifically
proven. Scientists have put UFOs in the category of pseudoscience."[50]
[edit] Animal activity
In 2009, the attorney general for the island state of Tasmania stated that Australian wallabies had
been found creating crop circles in fields of opium poppies, which are grown legally for
medicinal use, after consuming some of the opiate-laden poppies and running in circles.[51]
