On October 18, 1994, at approximately 14:00 hours, an off-duty gendarme (French military police officer) was foraging for mushrooms in the forests near Cerilly, Allier department in the Auvergne region of central France when he discovered an unusual ground trace. The witness encountered a circular formation composed of stone fragments or chips described as resembling 'mâchefer' (clinker or slag-like material). A particularly anomalous detail noted was that leaves in direct contact with these stones had turned a 'sulfurous green' color, suggesting possible chemical or thermal alteration. As nightfall approached, the gendarme decided to mark the location mentally and return the following day for further investigation and documentation. However, despite his training in observation and navigation, he was unable to relocate the site on his return visit. The case was officially reported to GEIPAN and classified as 'C' - indicating insufficient data to reach a definitive conclusion. This case presents several intriguing elements: the professional credibility of a law enforcement witness, the physical evidence of ground traces and altered vegetation, and the mysterious inability to relocate the site. No aerial phenomenon was directly observed, making this a 'trace case' rather than a sighting. The lack of photographic evidence, precise location data, and the single-witness nature limits investigative potential.

04 Analyst Notes -- AI Processed
The witness credibility is relatively high given his profession as a gendarme - law enforcement personnel typically receive training in observation and documentation. However, the inability to relocate the site despite professional training raises questions about either the witness's initial assessment of location markers or potentially disorienting environmental factors in the forest. The described physical evidence is significant: circular stone formations and chemically altered vegetation suggest either a natural geological/biological phenomenon or an event involving heat or chemical exposure. The 'sulfurous green' coloration of leaves is particularly noteworthy as it suggests chlorophyll degradation or chemical staining. The comparison to 'mâchefer' (industrial slag) is unusual for a natural forest setting. The circular pattern could indicate natural fungal activity (fairy rings), geological features, human activity, or something anomalous. The timing in mid-October during mushroom season explains the witness's presence in a potentially remote forest area. GEIPAN's 'C' classification indicates they found the report credible enough to document but lacked sufficient data for analysis - no samples were collected, no photographs taken, and the site could not be re-examined.
05 Theory Comparison
BELIEVER ANALYSIS
Landing Trace Evidence
The circular pattern, unusual stone material, and vegetation effects are consistent with other reported UAP landing trace cases. The sulfurous green coloration suggests possible radiation, electromagnetic effects, or chemical residue from propulsion systems. The witness's inability to relocate could indicate either deliberate concealment, perceptual manipulation, or temporal/spatial anomalies associated with high-strangeness events. Similar cases worldwide show circular ground traces with vegetation changes.
SKEPTIC ANALYSIS
Natural Phenomenon - Fairy Ring or Fungal Activity
The circular stone pattern may be a natural geological feature or the result of fungal activity. Certain fungi create circular patterns (fairy rings) and can cause soil discoloration. The stones could be naturally occurring mineral deposits or glacial erratic distribution. The green coloration might be natural chlorophyll breakdown, algae, or lichen growth common in damp forest conditions. The witness's inability to relocate suggests navigation error in unfamiliar dense forest terrain.
Human Activity - Abandoned Campfire or Forestry Marking
The circle could be remnants of an old campfire ring where stones were arranged by campers or forestry workers. The 'mâchefer' description suggests industrial slag, which might have been dumped or used as trail marking decades ago. Chemical contamination from old industrial waste could explain leaf discoloration. The site may have been partially obscured by fallen leaves or seasonal vegetation growth between visits.
06 Verdict
ANALYST VERDICT
This case most likely represents either a natural phenomenon misinterpreted in unusual lighting conditions, or a human-made feature (old campfire ring, forestry marking, agricultural remnant) encountered in an unfamiliar part of the forest. The inability to relocate the site suggests the witness may have been deeper in unfamiliar forest than realized, where navigation without landmarks is notoriously difficult. The 'sulfurous green' leaves could indicate natural leaf decay, fungal contamination, or reflection of filtered forest light. However, the case cannot be definitively explained without physical evidence or site examination. The witness's professional background prevents easy dismissal, but the lack of corroborating evidence or the anomalous phenomenon itself (no craft observed, no unusual lights) places this in the category of unexplained ground trace with insufficient data. It remains a minor curiosity in the GEIPAN archives - intriguing but ultimately inconclusive.
