Circular Evidence: A Detailed Investigation of the Flattened Swirled Crops Phenomenon
Pat Delgado, Colin Andrews

Something strange is happening in England. For the past 11 summers and possibly much longer, mysterious circles have appeared in the grain fields of Great Britain. Pat Delgado and Colin Andrews, engineers by profession, take the reader on a photographic tour of these remarkable formations. As you visit these sites with the authors you will see why the crop circles cannot be a hoax-and why they are still totally unexplained.
