History of crop circles
The earliest recorded crop circle is supposedly depicted in a 17th Century woodcut called the Mowing-Devil. The image depicts a strange creature creating a circular design in a field of corn. The legend suggests 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. Proponents of the belief that crop circles are either naturally caused, or are formed by as yet unknown entities, often support their viewpoint with this old tale. It is worth noting, however, that this is little more than a tale-the circular formation supposedly caused by the creature may be coincidental, or may have been caused by any number of natural or human processes.
Although the pixie circles created by Elves in Scandinavian folklore were most likely caused by fungus colonies, there was also a rarer kind, consisting of circular patches where the grass had been flattened:
On lake shores, where the forest met the lake, you could find elf circles. They were round places where the grass had been flattened like a floor. Elves had danced there. By Lake Tisaren, I have seen one of those. It could be dangerous and one could become ill if one had trodden over such a place or if one destroyed anything there (an account given in 1926, Hellström 1990:36)
Not long after WWII, the aerial surveys that were being made over large areas of Britain revealed some unexpected phenomena, undetectable from the ground. When the surveys photographed ripening crops or drought-stressed terrain they revealed what were soon termed "crop marks", the differential ripening of the crop that revealed differences in the subsoil. These patterns were found to be caused by the buried remnants of ancient buildings. Archaeological investigations were soon instigated, but, though many previously unsuspected archaeological sites were found, no crop circles were ever recorded. Skeptics argue that this would have pointed to circles as a modern phenomenon, even if the initial pranksters had not revealed themselves; believers reply different agendas may simply be at work in the modern day.
Crop Circles shot into prominence in the late 1970s as many circles began appearing throughout the English countryside. To date, thousands of circles have appeared at sites across the world, from disparate locations such as the former Soviet Union, the UK and Japan, as well as the US and Canada.
Crop circle designs
Early examples of this phenomenon were usually simple circular patterns of various sizes, which led some people to speculate that it was a natural phenomenon. But after some years more and more elaborate and complex geometric patterns have emerged.
There have been many recurring themes over the years. In general, the early formations (1970 - 2000) seemed to be based on the principles of Sacred Geometry. Later formations, those occurring after 2000, appear to be based on other principles, natural sciences and mathematics designs, including fractals. Many crop circles have fine intricate detail, regular symmetry and careful composition that suggest a high level of intelligence is responsible for their creation.
Sometimes complex crop illustrations have also appeared, including cartoon characters.
Contending beliefs
Most critical observers, and the scientific mainstream, are convinced that crop circles are sniggles or hoaxes engineered by humans. This explanation, supported by the documentation produced by some crop-circle hoaxers, has the advantage of not requiring us first to assume the existence of flying saucers or other as-yet-unobserved phenomena. However, there are many contending hypotheses which assume that at least some crop circles are not the products of mundane hoaxers; these hypotheses vary in their degree of scientific rigor, but all fall to some extent outside the mainstream.
One modern unscientific belief, is that crop circles are created by flying saucers landing in fields and flattening a neat circle in the crop. However, the increasing complexity of formations from the 1980s on, and the implausibility of the idea that extraterrestrial beings would travel to Earth for the sole apparent reason of flattening crops, make this conjecture seem unlikely.
Some pseudoscientifically inclined enthusiasts suggest that an explanation more plausible than flying saucers might be cymatics, the visualisation of vibration or sound. According to this hypothesis, the complex patterns are two-dimensional geometric or visual representations of sound frequencies, with higher sound frequencies producing more complex shapes similar to both mandalas and crop circle designs.
Another pseudoscientific hypothesis is that a man-made satellite in Earth orbit is using some kind of beam (e.g., microwaves) to create the designs. Heating stems of wheat with a short intense burst of microwave energy can produce wilting similar to that in a crop circle. Flattened stems often have the bend just below a stem-node, and also may feature blackened burn holes indicative of intense heating. Microwave heating has been shown to be capable of producing these effects. It is postulated by believers of this theory that the U.S. Pentagon's "Star Wars" program has a satellite capable of delivering such a microwave beam.
Often touted as evidence for the mystic origin of crop circles is the coincidence that many circles in the Avebury area of southern England occur near ancient sites such as earth barrows or mounds, white horses carved in the chalk hills, and stone circles. Other ideas on their formation have been proposed include tornadoes, freak wind patterns, ball lightning, and something called "plasma vortices".
A number of witnesses claim to have observed circles being created, saying that it takes a few seconds and the corn falls flat like a fan being opened - though these accounts are always anecdotal and have never been supported by any evidence beyond the claimants' assertions. Crop circle enthusiasts, though they do not always have scientific backgrounds or credentials, claim that there are other features of crop circles that undercut the hoax theory. They say that bends in the corn in many circles occur just below a joint, while the flattening of the corn by hoaxers produces a crack at any point in the stem, and some scientific studies on apical nodes bear them out. Also they say that flattened corn often lies in groomed layers, rather than random crushings. While there have been cases in which believers declared crop circles to be 'the real thing', only to be confronted soon after with the people who created the circle and documented the fraud, the bending issue remains in dispute. For this reason, skeptics prefer the explanation that there are simply different hoaxers employing different techniques.
Hoaxed circles
In 1991, more than a decade after the phenomena began, two men announced that many crop circles were a hoax of their doing. Doug Bower and Dave Chorley revealed that they had been making crop circles since 1978 using planks, rope, hats and wire as their only tools. Bower and Chorley stated to reporters that a small group of people can stomp down a sizeable area of crop in a single night. "Stomp" does not mean using the feet: simple tools to make crop circles have been demonstrated. [2].
Circlemakers.org, the most famous group of crop circle makers founded by John Lundberg have demonstrated that making what self-appointed cerealogist experts state are "unfakeable" crop circles is possible. One such cerealogist, G. Terence Meaden, was filmed claiming that a crop circle was genuine when the night before the making of that crop circle by humans was filmed. On the night of July 11-12, 1992, a crop-circle making competition, for a prize of several thousand pounds (partly funded by the Arthur Koestler Foundation), was held in Berkshire. The winning entry was produced by three helicopter engineers, using rope, PVC pipe, a trestle and a ladder. Another competitor used a small garden roller, a plank and some rope. The size and complexity of the designs produced demonstrated the minimal equipment and preparation required to produce a crop design, lending even more credence to the hypothesis that this phenomenon is purely and solely the result of humans playing pranks.
Scientific American published an article by Matt Ridley (August 2002, p. 25), who started making crop circles in Texas 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 to create a hoaxed crop circle have been well-documented on the Internet.
A counter argument to hoaxing is that where circles appear in crops mature enough that they carry seeds (as they do so often) seed-pods are unbroken, whereas trampling causes seed-pod breakage. Crop circle hoaxers counter that it is easy to leave dry seed pods unbroken during stomping and also leave no trace of entrance and egress trampling when the plants and ground are both dry and some care is taken while walking. Several crop circles that were later to have been determined to be hoaxes were at first certified as being genuine by cerealogists due to the lack of seed pod breakage. Entry to a field without leaving traces is also easy, since there always are several tracks made by the machines used to spray insecticides on the crop that people can use.
Some claim that the circles might still have merit as a social phenomenon regardless of their legitimacy. New Age experts have expressed interest in researching the shapes and symbols depicted.
Circlemaker Matthew Williams was the first circlemaker ever to be arrested and charged with criminal damage to farmland in 2000. Since then, Matthew has gone on to give many public demonstrations on how circles are made in complete darkness with simple tools such as a tape measure and board.
Some crop-circle photographs are hoaxes, created using image manipulation.
