Wiltshire Crop Circles (1980–1991)

Origins and growth

Flattened crop formations had been reported sporadically for centuries, but the modern phenomenon is usually dated to the late 1970s and early 1980s in Wiltshire, where the county had also been a focus of 1960s UFO reports. The PSI Encyclopedia, published by the Society for Psychical Research, describes Wiltshire as the principal crop-circle site by the 1970s, with reports climbing from the early 1980s to 112 in 1988, 305 in 1989 and almost 1,000 in 1990. Formations grew more elaborate, with clustering around Westbury, Winchester and the Avebury area. Journalist Jim Schnabel's Round in Circles (1994) traced the phenomenon from its 1980 Wiltshire beginnings through the people it drew in, from plasma physicists to the circle artists themselves.

The hoax admissions

The turning point came in 1991, when Doug Bower and Dave Chorley publicly claimed they had made more than 200 circles since 1978, using a plank, rope and a cap fitted with a wire loop to keep lines straight. Wikipedia's crop circle article reports that they demonstrated the method to journalists, and that a believer, Pat Delgado, had declared one of their test circles genuine before the reveal. Their account was not the first admission: in July 1990 Mike Jay said he had made the Etchilhampton Formation, which Delgado and Colin Andrews had attributed to non-human causes. Copycats followed quickly, some of them styling themselves as circle artists. The UK arts collective Circlemakers, founded in the early 1990s by Rod Dickinson and John Lundberg, now makes formations as art and for commercial clients, and in 2009 reproduced a complex design for National Geographic.

The case for non-human causes

Believers, called cerealogists or "croppies", offered several explanations. George Meaden proposed a larger, ball-lightning-like "plasma vortex" in 1989 and 1991; Stephen Hawking's 1991 remark that circles were "either hoaxes or formed by vortex movement of air" was widely quoted. Colin Andrews argued for electrostatic fields from underground water, and later claims included radiation in soil and plants and, in 1996, a long formation near Stonehenge that some interpreted as non-human. Researchers associated with the BLT team, notably W. C. Levengood, published plant-deformity studies that they argued showed anomalous energy. Meaden conceded by late 1991 that complex designs were made by people, and Joe Nickell challenged Levengood's plant-deformity work in 1996 as circular reasoning that failed to establish causation.

Current assessment

The balance of evidence now favors human authorship for the great majority of formations. Carl Sagan, in The Demon-Haunted World, concluded that Bower, Chorley and their copycats made the circles. Iain Murray's 2002 Christian Science Monitor report noted that believers rejected the confession by arguing that stalks cannot bend without breaking and that the absence of tracks ruled out hoaxers, while hoaxers such as Fred Day had described working on stilts; the 2002 film Signs revived the mystery in popular culture. Writer Matt Ridley's critical 1992 Daily Telegraph pieces drew accusations of government disinformation, and Ridley argued that believers had financial and reputational reasons to resist human causation.

The phenomenon is therefore best described as a documented hoax tradition that generated a durable belief system. The early Wiltshire formations are a useful case study in how a striking visual puzzle, amplified by media attention and observer clustering, can persist long after its most visible explanations have been withdrawn. The sources also disagree on the exact start date (1976, 1978 and 1980 all appear), and on whether Bower and Chorley's confession came in 1991 or later; the 1991 date is the one most consistently reported.
