Books & Articles:
John Burke (the "B" in BLT) and Kaj Halberg present scientific
evidence that the engineers who built many of the massive
monuments of the ancient world may have known a secret.
The henges, pyramids, mounds & dolmen were overwhelmingly
sited where local geology magnified naturally-occurring EM
fluctuations—energies which were enhanced by the structures
built there. Addtionally, they show that seeds placed at these
sites subsequently demonstrate increased growth-rate and
yield, a discovery that may explain why these mysterious stone
structures appeared all over the world. (Book Details)
"The Physics of Crop Formations," written by John Burke
(MUFON Journal, October 1998, pp. 3-7), presents a detailed
explanation of the rationale behind W. C. Levengood's
hypothesis that crop circles may be the result of highly energetic,
thermodynamically-unstable atmospheric plasma energy
systems impacting the earth's surface.


"Origin of Crop Circles Baffles Scientists," written by well-
known investigative reporter Leslie Kean, was published on
September 16, 2002 in Rhode Island's The Providence Journal ,
and was the first comprehensive article published in the U.S.
covering the BLT Research Team's work.


Other articles written by Nancy Talbott or John Burke for farm journals and the "anomalous phenomena" audience have been published in specialty publications. Newspapers in the U.S., Canada and Europe have presented some of the laboratory results obtained by the BLT Research Team, but most frequently in inadequate detail. A major article did appear in The London Times Sunday Magazine several years ago, which featured the results presented in 2004 in BLT's x-ray diffraction study of clay minerals in crop circle soils.
