Geometric Vegetation Markers (saucer nests → crop circles)

On January 19, 1966, rural worker George Pedley (28) reported observing a metallic disc roughly 7.5m wide rising from Horseshoe Lagoon near Tully, Queensland. At the site he found a circular depression of about 9m of flattened reeds he called a 'nest'. Five additional nests were later found. The Royal Australian Air Force (RAAF) conducted an official investigation — the first sample-analysis investigation in Australia. The RAAF conclusion was that the reeds died 'from natural submersion'; the University of Queensland attributed the patterns to 'severe turbulence' compatible with regional line squalls. The case is the first 'crop-circle' paradigm with documented official military investigation, a chronological parallel of Westall (same year, different modus).

On September 9, 1991, the British tabloid ''Today'' published the confession of two men from Southampton, Doug Bower and Dave Chorley, who claimed to have created circles in the crop fields of southern England since 1978. Their tool was trivial: a wooden plank tied with a rope, plus a cap with a wire sight to walk in a straight line. Inspired by the Tully ''saucer nests'' (Australia, 1966), they wanted to simulate the landing of a UFO. They demonstrated the method to journalists and, before revealing the trick, got the cerealogist Pat Delgado to declare one of their circles ''genuine''. The confession deflated much of the simple crop-circle phenomenon and established the copycat pattern that followed. It is the corpus's documented, confessed hoax par excellence.
