Since the late seventies enigmatic circles and geometric patterns have appeared in the crop fields of England. The pictograms have both baffled scientists and the general public raising many question as to their generation and means of origin.

A Crop Circle is most notably signified by an overnight appearance of a design or "circle" in various kinds of cereal crop including grain, barley, oats, rape, oil seed, and wheat. They can range in size from twenty to a thousand feet in size. A true crop circle is not "cut" into the crop but rather vorticularly impressed by an as of yet undetermined source. According to researchers like Colin Andrews, the actual construction of a crop circle is very intricate and orderly with a meticulous attention paid to not breaking the stems of the crop but rather bending and interweaving of the stems to form the a spiriling floor pattern. The importance of this is that the wheat is not broken, as if done by human intervention but rather bent at what are called "nodes" of the crop stalks. A node is a point where the stalk is adjoined to another section of the stalk. Normally these are erect and rigid, but inside a crop circle pattern they have been altered to bend in the direction of the floor pattern, or direction of flow of the crop.
