Crops · 17 recorded · two of the three sites record one
What the fields were growing
A crop is what a source printed beside a formation, folded to one of these names. It dates a season as surely as a calendar — rape is flattened in April and May, barley in June, wheat in July and August, maize into the autumn — and it is the one thing about a formation a photograph shows without anyone's say-so.
A colour is a label, never a measurement
Each crop has one hue on this site, used for the disc on a record plate and the swatch beside a name. It is a key, like a map legend; it says nothing about the field. Where the crop is written two ways by two sources, the page prints both spellings and folds them to one.
The year, crop by crop
reports by month · the 4 crops that carry most of the archiveEach row is one crop; each cell is how many formations were reported in that crop in that month, every year of the archive together. The shape is the farming year seen through the reports.
A cell's tint is that crop's own hue at the month's share of that crop's reports, so a small crop still shows its season. The row total is every formation in the crop, including the 84 across these 4 crops that no source gives a month to and that therefore appear in no cell.
The 17 crops, and the formations with none
most formations first · names as folded, spellings as printedRead the gap, not just the counts
crop is recorded by cropcirclecenter.com and temporarytemples.co.uk only; cropcircleconnector.com records none, so a formation known from that site alone is listed under “not recorded” rather than under a crop it may well have had.
The disc in each card is the record-plate disc at that crop's hue: solid where a crop is recorded, dashed grey for the formations no source gave one for. The spellings are the ones the sources printed on the records this build read.
How a crop is shown on a record
Three states, one component. The disc's size is the formation's own recorded diameter against a 60 m field; its colour is the crop. Where the archive may show no picture of a formation, this is what its plate draws — never a guess at the design.
