Singles and Quintuplet; Single in Sugerbeet
There is a record of the classic 'five-on-a-dice' configuration having appeared in the 1950's. Alongside it is a report of other single circles in the vicinity, including one in sugar beet.
Heytesbury is a small village south east of Warminster in Wiltshire,
and therefore within an area where crop circle reports are particularly
numerous. Further details currently elude us however.It is
popularly thought that the first quintuplet formation was recorded at
Cheesefoot Head in Hampshire in 1983. However this is a misconception
caused by the photographic selections in the book Circular Evidence.
In fact, besides the case suggested above, Circular Evidence contains references to an earlier one at Headbourne Worthy in 1978.
There also exists evidence of a quintuplet in Mexico in 1977. Yet another was recorded in Australia, also in 1977 (but thought to be a ground marking of some sort, rather than a crop circle).
