Crop Circles

A 'crop circle' or 'crop formation' is a pattern created by flattening a crop, usually a cereal. The term was first coined in the early 1980s by Colin Andrews. Although obscure natural causes or alien origins of crop circles are suggested by some theorists, there is no scientific evidence for such explanations. Human causes are consistent for all crop circles.

The number of crop circles has substantially increased from the 1970s to current times. There has been little scientific study of them. Circles in the United Kingdom are not spread randomly across the landscape but appear near roads, areas of medium to dense population and cultural heritage monuments, such as Stonehenge.

In 1991, two hoaxers, Bower and Chorley, took credit for having created many circles throughout England after one of their circles was described by a circle investigator as impossible to be made by human hand. Formations are usually created overnight, although some are reported to have appeared during the day.
