Geophysical surveys and geometry of crop circles

Detectable magnetic anomalies in crop circles and geometrical construction of crop-circles' shapes

Project Argus 1992

Argus is the name of a scientific research project, that investigated crop circles. In the summer of 1992, Project Argus investigated one of the most remarkable mysteries of the century, the sudden and baffling appearance of hundreds of huge, magnificent shapes - dubbed "crop circles" - in the fields of England each summer.
