a Crop Circle
"The Underground Connection" is interesting look at the
relationship between the underground water-table and the placement
of crop circles in England during the years 1993-1998. This research
supports a later discovery by John Burke that ground electrical charge
in Wiltshire County (where a majority of the British crop circles
occur each summer) increases slightly over the summer, as the water-table
lowers. Such an increase in ground electrical charge may function
as an "attractor" to W.C. Levengood's hypothesized plasma
vortex energy system as the causative mechanism behind the phenomenon.
Additional professional research into the crop circle phenomenon is relatively sparse -- partially, we suspect, because the mass media attributes crop circles to "pranks with planks" (manual flattening of the crops by people) which has resulted in there being little funding available to support serious scientific inquiry. We list below a few links to other work which has been carried out which may be of interest.
H-GLAZE REPORT: In 1993, during the Perseid meteor
shower in August, a crop formation occurred in Wiltshire, at Cherhill.
This formation was remarkable primarily because of a "metallic
glaze" that was observed on the plants in some of the swirled
sections of the formation. This material was sampled by the first
visitors to the formation and some of these samples were sent immediately
to W.C. Levengood and John Burke in the U.S. for analysis. Levengood
and Burke's peer-reviewed paper, "Semi-Molten Meteoric
Iron Associated with a Crop Formation"
was published in 1995 in the J. Sci. Exploration.
In 2001 Rodney Ashby, an Englishman interested in the crop circle
phenomenon, posted a report on his web-site entitled "The
H-Glaze Report," which presented a detailed account
of his examination of samples he had received in 2001 (8 yrs. after
the original event) – materials purportedly recovered from the
same 1993 Cherhill, UK crop formation. Mr. Ashby's original 2001 report
supported many of the findings presented in the Levengood/Burke paper,
in particular the evidence pointing to intense heat having been involved. For reasons known only to Mr. Ashby, he has now (2010) removed his original "The H-Glaze Report" paper which supported the Levengood/Burke research--it is no longer present anywhere on his web-site. Anyone interested in reading this original paper should contact Nancy Talbott in the BLT office.
In early 2005 Mr. Ashby posted a second report, "The
H-Glaze Explained," in which he states that he has examined
a material "recently" supplied to him (by a self-proclaimed
crop circle hoaxer) -- which material he now believes to be the source
of the magnetic material discussed in both the Levengood/Burke 1995
paper and his own original H-Glaze report.
Because there were inconsistencies in Mr. Ashby's two reports, as
well as a number of facts presented in the Levengood/Burke paper which
Mr. Ashby did not address at all, Levengood and Burke have issued
their "Comments" on Ashby's 2005 posting,
which can be read at the following web-site:
SHORT-LIVED RADIONUCLIDES: A 1991 study published by Marshall Dudley and a co-author reported the discovery of 13 short-lived radionuclides in soil samples from one British crop circle. A second paper (a retraction of the 1991 results), written by the same authors and withdrawing most of the 1991 paper's claims, was apparently subsequently published. Now (2012) Mr. Dudley's co-author has requested that BLT remove his name from the 1991 study and also the link. Since BLT has been unable to obtain a copy of (or a link to) the later retraction we have removed the original link and suggest interested parties contact Marshall Dudley in Durham, N.C.

METEOROLOGICAL INTERPRETATION: British meteorologist George
Terence Meaden spent considerable time investigating crop circles
in the 1980s and came to the conclusion that "simple" circles were
caused by local wind vortices and that all others were man-made. He
authored several books which are now, unfortunately, out of print,
but he has posted a summary of his opinion on the web and can be contacted
for further comment.

GEOMETRY & CROP CIRCLES: Many individuals interested in crop circles have been intrigued by the complex geometry inherent in a number of formations. How such precision is accomplished on undulating and/or sloping fields, covering large areas of ground, in the dark of night and in all types of weather, stimulates real curiosity. The fact that many of the standing-crop elements found inside crop circle perimeters could have only been referenced from external points in the cropfield -- where the crop is found to be untouched -- adds to the mystery. There are many web-sties which investigate this aspect of the circles; here are a few:
Gerald S. Hawkins,
Ph.D, D.Sc, former Chairman of the Dept. of Astronomy, Boston University,
has found that some crop circle patterns embody geometric theorems
and diatonic ratios (the simple whole-number ratios which determine
a scale of musical notes).
Hawkins also discovered a fifth, more general, Euclidean theorem,
from which he could derive the other four. However he could find no
reference to this fifth theorem in the works of Euclid or elsewhere,
and he subsequently challenged the readers of both Science News
and The Mathematics Teacher to come up with this unpublished
theorem. See the article published in Science News (Oct. 12, 1996)
Bert Jansen, also from The Netherlands, is a producer, photographer
and award-winning videographer in the crop circle field who is also
writing a booklet on the geometry found in crop circles. (Click on
"Crop Circles" on left-hand side, then scroll down to "Crop Circle
Reconstructions" & "Crop Circle Geometry.")

Zef Damen, PhD., a Dutch electrical engineer in the tele-communications
industry provides step-by-step constructions of a number of crop circles,
showing the basic geometries involved.
Judy Arndt, an Alberta, Canada crop circle fieldworker and
photographer, has also included analyses of geometries found in some
of the Canadian circles she presents.
