Crop circles have always fascinated me. The hoaxes as well as the unexplained. One of the aspects of crop circles that I find interesting is that they have been doing soil samplings of the circles, and what they hae come up with, is that the soil has unusually high quantities of nitrogen after a formation has appeared.
Also, as several articles explained, "..there are significant differences between normal plants and those taken from crop circles, leading the team to conclude that the observed electromagnetic changes are impossible to hoax through mechanical flattening of crops".
Here is some interesting information regarding crop circles, as well as information about the crop circles that have not been able to be explained through the hoaxes.
Please do read as it is very interesting as well as informative.
An article showing geometric theorem linked to music through a crop circle. Something never heard of prior to this:
Several years ago, astronomer Gerald S. Hawkins, former Chairman of the astronomy department at Boston University, noticed that some of the most visually striking of the crop-circle patterns embodied geometric theorems that express specific numerical relationships among the areas of various circles, triangles, and other shapes making up the patterns (Science News: 2/1/92, p. 76). In one case, for example, an equilateral triangle fitted snugly between an outer and an inner circle. It turns out that the area of the outer circle is precisely four times that of the inner circle.Three other patterns also displayed exact numerical relationships, all of them involving a diatonic ratio, the simple whole-number ratios that determine a scale of musical notes. "These designs demonstrate the remarkable mathematical ability of their creators," Hawkins comments.Hawkins found that he could use the principles of Euclidean geometry to prove four theorems derived from the relationships among the areas depicted in crop circles. He also discovered a fifth, more general theorem, from which he could derive the other four (see diagram, left). "This theorem involves concentric circles which touch the sides of a triangle, and as the [triangle] changes shape, it generates the special crop-circle geometries," he says.Hawkins' fifth crop-circle theorem involves a triangle and various concentric circles touching the triangle's sides and corners. Different triangles give different sets of circles. An equilateral triangle produces one of the observed crop-circle patterns; three isosceles triangles generate the other crop-circle geometries.What is most surprising is that all geometries give diatonic (musical) ratios. Never before have geometric theorems been linked with music. Curiously, Hawkins could find no reference to such a theorem in the works of Euclid or in any other book that he consulted. When he challenged readers of Science News and The Mathematics Teacher to come up with his unpublished theorem, given only the four variations, no one reported success.In July 1995, however, "the crop-circle makers . . . showed knowledge of this fifth theorem," Hawkins reports. Among the dozens of circles surreptitiously laid down in the wheat fields of England, one pattern fit Hawkins' theorem based on the stringent definitions, on the rules established by the circles over the period 1980 to the present.The Circlemakers responsible for this old-fashioned type of mathematical ingenuity remain at large and unknown. Their handiwork flaunts a facility with Euclidean geometry and signals an astonishing ability to bend living plants without cracking stalks, and to trace out complex, precise patterns, most under cover of darkness, with a few notable exceptions during daytime.
NOTE: The circlemakers' fifth theorem has been published in the Mathematics Teacher, the magazine of the National Council of Teachers of Mathematics.

The following article compares two leading theories of crop circle formation. The "plasma event" (usually "plasma vortex") theory invokes an electromagnetic event which creates a rapid heating effect, causing patterns to be imprinted in grains, snow, sand and other media. The "mechanical flattening" hypothesis assumes that human artists create all formations using rollers, boards, rope and an array of other technologies.

More interesting information regarding scientific studies of soil, affects on plants, etc.. from crop circles. Includes a couple of photos of the damage done to plants that have nothing to do with the process that hoaxsters use to create crop circles.
