In the summer of 1981, Pat Delgado drew attention to the existence of some mysterious circular depressions in the fields at Cheesefoot Head, Hampshire. Other similar phenomena in southern Britain have also been found. Theories about their origin abound and this book discusses them.

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.
