1975 and 1976 - Headbourne Worthy
These two single circles, found a year apart, are significant for the history or crop circles. When the two hoax claimants Doug Bower and Dave Chorley came forward in 1991, they claimed to have made the first ever crop circle in 1978, which happens to match the first case study in Circular Evidence.
They were of course unaware that the owner of the land, Ian Stevens, had witnessed circles in the years prior to this, just a few miles away from where Doug & Dave claimed to have started it.
The 1975 circle was publicly unknown until 1992, when Colin Andrews published details for the first time, in his CPRI Newsletter (volume 1, no. 2). He describes the earlier circle as "about 60 feet / 18.28 metres diameter... flattened to the gound and spiralled." Mention of the 1976 circle is made in Circular Evidence (right).
He also provided a sketch showing the location of the two Heabourne Worthy events together (see below).There is a discrepancy in the detail: in his diagram, the 1976 circle is to the east of the A34. However the report in Circular Evidence gives the location as "the western side of the A34". The map is almost certainly correct on the issue.
Below is Colin's diagram of the two events, and a satellite image illustrating where they appeared, based on the map and grid references in Andrews' newsletter. The land use has changed where the 1976 circle appeared, and it is no longer sown with crops. There is now a motor cross circuit in that part of the field.
