crop circles

Crop circles are sizeable patterns created by the flattening of crops such as wheat, barley, rye, or maize. The term crop circle entered the Oxford Dictionary in 1990. In 1991, self-described pranksters Doug Bower and Dave Chorley confessed that they started the crop circle phenomenon in 1978. Their work is continued by other groups of crop circle makers such as the circlemakers arts collective founded by John Lundberg in the early 1990s. Prior to this admission, many seriously entertained the idea that crop circles were not man-made, and even after the disclosure of the prank, there were paranormal enthusiasts, ufologists, and anomalistic investigators who continued to offer alternative explanations which are heavily criticized by skeptical groups such as the Committee for Skeptical Inquiry.
