Crop circles have appeared throughout the world long before the infamous Dave and Doug duo began misleading the world about their grain-stomping pranks in 1991. The earliest accounts of crop circle formations were documented by Robert Plot, then curator of the Ashmolean, in 1678. Dozens of eyewitnesses reported these crop circles forming in a matter of seconds as early as 1890.

To date some 10,000 crop circles have been catalogued worldwide, and their anomalous features continue to be irreplecatable: plants bent an inch above soil and gently laid down in geometrically-precise patterns with no physical signs of damage, light burn marks at the base of stems, altered cellular structure and soil chemistry, discrepancies in background radiation, alteration of the local electromagnetic field, depletion of the local watershed, and dowsable, long-lasting energy patterns, not to mention measured effects on the human biological field. So much, then, for two guys and a piece of wood. But thanks to a virtual embargo on research coverage throughout the media, a popular myth has developed that all crop circles have been nothing more than a prank with a plank.

The above quote was taken from an extract of Secrets in the Fields. Scientists believe that they may have the answer to the cause of these crop circle formation–sound. Click on the links to read about their discoveries.

Many witnesses have described hearing a trilling sound, followed by a sudden stillness in the air. They would watch the wheat heads bang together, despite this stillness. Then a whole section of crop flattens to the ground in a spiral pattern in less than fifteen seconds.

Can you imagine being there and watching this happen?
