Circular Evidence: A Detailed Investigation of the Flattened Swirled Crops Phenomenon

The 1981 discovery of mysterious and beautiful circular depressions in fields of crops in southern Britain has initiated a full and scientific investigation by the authors, who are founder members of the Circles Phenomenon Research Group. They have interviewed farmers and witnesses, made location visits, taken photographs and measurements and tested theories. Reports of further anomolous occurrences, mysterious coincidences possibly connnected with the circles and related observations from other countries are also included in the text.
