A number of recent crop formations have been truly incredibe, completly impossible to produce by any known means. An excellent example is the huge formation at Etchilhampton, which displays a ring of woven wheat of an intircacy that cannot be explained. A formation such as this could not be made, for example, by some sort of a laser device pointing down from above, because the wheat must be literally woven like a carpet, and done without breaking the dry stems. Another at Roundway Hill near Devizes is also extraordinarily intricate and beautiful.
