Crop Circles

Crop circles celebrated twenty five years of age this year. This little known fact will come as a surprise to most people. It will also be somewhat of a revelation to many that when this phenomenon began on that fateful night in Warminster, England, it was in very modest terms in the form of a simple, elegant circle of pressed wheat some 30 ft in diameter. Two and a half decades and some 9000 formations later, crop circles have grown into complex mathematical fractals, in lengths up to three quarters of a mile, in area coverage as large as 36,000 square ft, and in geographic location. Crop circles- or agriglyphs- can now be found in most countries around the globe. The issue is that no man-made crop circle has satisfactorily replicated the features associated with the real phenomenon which has baffled scientists and researchers.Worldwide, some 4000 crop circles have been created by a force totally at odds with modern science.

Anatomical anomalies in crop formation plants

W. C. Levengood, BLT Research Team (published in Physiologia Plantarum)

In the present paper. evidence is presented which indicates that structural and cellular alterations take place in plants exposed within the confines of the 'circle' type formations. differences which were determined to be statistically significant when compared with control plants taken outside the formations. These transformations were manifested at the macroscopic level as abnormal nodal swelling. gross malformations during embryogenesis, and charred epidermal tissue. Significant changes in seed germination and development were found. and at the microscopic level differences were observed in cell wall pit structures. Affected plants also have characteristics suggesting the involvement of transient high temperatures.

Boy In Holland Claims To Have Witnessed Crop Formation

Nancy Talbot, Director, BLT Crop Circle Research Team

"This event is in southern Holland - and it's concerning again this boy, Robert van den Broeke, who has the ability somehow to know when these things are getting ready to happen and who has been in the middle of a formation when it occurred - this was a couple of years ago. R

Circles of Note: Bibliography on the Crop Circles

Michael Chorost

Bibliographies always look rather dry. However, a careful reader can learn much from this one, since many of the entries have parentheti- cal summaries attached to them. Also, a close look at the topics will reveal the diversity of the crop circles phenomenon and the responses it has gathered. Finally, the sections on books, magazines, and studies include price and ordering information, where known. R

Crop Circles: Artworks or Alien Signs?

Hillary Mayell, National Geographic News, August 2, 2002

Mel Gibson's new film, Signs, is reviving public interest in the phenomenon of crop circles. It would be unfair to reveal what it is that's scaring Mel so badly in the world of movies. In the real world, the battle to explain the formations is a torrid wrestling match between artists and people who believe in other-worldly influences.  R

Crop Circles: Plant Abnormalities

BLT Research Team

The physical changes (listed below) documented in crop circle plants by Michigan biophysicist W.C. Levengood have been determined by evaluating hundreds of sample plants -- both downed and standing -- taken from inside the overall perimeter of each formation against hundreds of control plants taken at varying distances outside each formation, in several directions. More than 350 individual crop formations from multiple countries, over a 10-yr. period were examined.

Crop Circles: 'Signs from Above' or Human Artifacts?

Jacques Vallee

The early formations were simple circles, then circles with satellites. In later years more and more sophisticated and precisely-drawn geometric figures appeared. All the significant formations were observed in an area in close proximity to major research facilities of the British defense establishment, often in controlled airspace.  R

Crop Circles: The Formative Years 1972-1989

Freddy SIlva, The Crop Circular

So, by the appearance of a modest, elegant circle of pressed wheat some 30 ft in diameter in southern England began the study of crop circles in our era. Two and a half decades and some 10,000 formations later, crop circles have grown into complex mathematical fractals, in lengths up to three quarters of a mile, and covering areas as large as 200,000 square ft. Crop circles- or agriglyphs- can now be found in most countries around the globe.  R

Findings of a Magnetic Signature in some Crop Circles

Colin Andrews - 18th August 2000

An estimated 20% of crop circles show no evidence of being made by people, while 80% do. On Wednesday the 9th of August, I announced on national television and radio the outcome of an ongoing investigation into aspects of the crop circle mystery.  R

Origin of Crop Circles Baffles Scientists

Leslie Kean, The Providence Journal

SINCE THE RECENT release of the movie Signs, crop circles have been thrust into the limelight. Such major publications as Scientific American and U.S. News and World Report have echoed the common belief that all crop circles are made by stealthy humans flattening plants with boards. This assumption would be fair enough if we had no information suggesting otherwise. However, intriguing data published in peer-reviewed scientific journals clearly establishes that some of these geometric designs, found in dozens of countries, are not made by "pranks with planks." In fact, a study about to be published by a team of scientists and funded by Laurance Rockefeller concludes "it is possible that we are observing the effects of a new or as yet undiscovered energy source."  R

The Crop Circle Phenomenon - A Beginner's Guide

Andy Thomas (Swirled News)

Huge, complex and beautiful patterns are being found swirled into crop fields around the world every year. Their origin and purpose remains a complete mystery. Despite attempts to dismiss them as the work of human artists, some believe the evidence points to a much stranger explanation. Wherever they come from, these spectacular designs often display very clear symbolism, scientific, esoteric and astronomical, and demonstrate some extraordinary unexplained effects. R

BLT Research Team

The BLT Research Team Inc.'s primary goal is the discovery and scientific documentation of physical changes induced in plants, soils and other materials at crop circle sites by the energy (or energy system) responsible for creating them and to determine, if possible, from these data the specific nature and source of these energies. Secondly, our intent is to publish these research results in peer-reviewed scientific journals and to disseminate this information to the general public.

Canadian Crop Circle Research Network (CCCRN)

A non-profit research organization which has been investigating the crop circle phenomenon and other possibly related phenomena in Canada since 1995, creating a liason between researchers, farmers, scientists, media and the public; it is the only such group of researchers specifically investigating Canadian formations on an ongoing basis.
