On June 12, 1981, in late afternoon, an agricultural worker discovered unusual ground traces in a cornfield in Barbezieux, Charente department, France. The witness found a circular zone approximately 20 meters in diameter where corn plants appeared diseased or damaged. At the center, several plants had completely disappeared, while surrounding plants were desiccated as if subjected to intense heat, with the effect diminishing progressively with distance from the center and disappearing completely at about 10 meters out. The central area displayed cracked earth with an 80-centimeter depression containing five holes, each 4-5 cm in diameter and approximately 20 cm deep, arranged in a trapezoid pattern. An indefinable odor persisted at the center of the circle. The discovery prompted an official GEIPAN investigation, and soil and vegetation samples were collected for laboratory analysis. Laboratory analysis confirmed that the central zone had been subjected to significant heat exposure. Soil samples from the center showed markedly lower moisture content compared to samples taken from the periphery, indicating temperatures probably exceeding 100°C had affected the area. Meteorological data revealed that a violent storm with heavy rainfall had struck the region during the night of June 8-9, three to four days before the discovery. GEIPAN investigators concluded that lightning strike was the most probable cause, as it could explain the blast effect on the corn plants, the temperature increase, and the characteristic ground holes caused by electrical currents induced in the soil.
02 Timeline of Events
1981-06-08 night
Violent Storm Strikes Region
A violent storm with heavy rainfall affects the Barbezieux area. Meteorological data confirms significant electrical activity in the region during this period.
1981-06-09 early morning
Suspected Lightning Strike
Probable lightning strike occurs in cornfield, creating ground traces and heat damage. Event goes unwitnessed during nighttime storm conditions.
1981-06-12 late afternoon
Ground Traces Discovered
Agricultural worker discovers 20-meter diameter circular zone of damaged corn plants with distinctive central ground features including depression and holes.
1981-06-12 evening
Investigation Initiated
Official GEIPAN investigation begins. Site examination conducted and samples of soil and vegetation collected from various points within the affected zone.
1981-06 post-discovery
Laboratory Analysis Completed
Scientific analysis confirms central zone experienced temperatures exceeding 100°C, with significantly reduced soil moisture compared to peripheral samples.
1981-06 investigation conclusion
Lightning Strike Hypothesis Confirmed
GEIPAN concludes investigation with 'B' classification (probable identification). Lightning strike determined most likely explanation based on physical evidence, meteorological data, and laboratory results.

Anonymous Agricultural Worker
Agricultural worker/farmer
medium
Local agricultural worker who discovered the anomalous ground traces while working in a cornfield in Barbezieux. Witness discovered physical evidence rather than observing an aerial phenomenon directly.
"The witness discovered a circular zone approximately 20 meters in diameter where corn plants appeared diseased, with plants at the center completely disappeared and others desiccated as if subjected to intense heat."
04 Analyst Notes -- AI Processed
This case represents a well-documented ground trace investigation with physical evidence collection and scientific analysis. The GEIPAN classification of 'B' indicates a probable explanation has been identified with good confidence. Several factors support the lightning strike hypothesis: (1) documented severe weather in the area 3-4 days prior, (2) laboratory-confirmed heat damage exceeding 100°C, (3) characteristic pattern of damage radiating from a central point, (4) ground holes consistent with electrical discharge patterns, and (5) the trapezoid arrangement of holes matching typical fulgurite formations. The credibility of this case is strengthened by the systematic investigation approach, including sample collection and laboratory analysis rather than relying solely on witness testimony. The time gap between the suspected lightning event (night of June 8-9) and discovery (afternoon of June 12) is consistent with a farmer noticing anomalous crop damage during routine fieldwork. The lingering 'indefinable odor' could be explained by ozone production or organic material combustion from the lightning strike. While the witness did not observe the actual event, the physical evidence provides objective data for analysis. This case serves as an example of how systematic scientific investigation can identify mundane explanations for initially mysterious ground traces.
05 Theory Comparison
BELIEVER ANALYSIS
SKEPTIC ANALYSIS
Agricultural or Industrial Cause
A skeptical alternative might consider whether agricultural activities, chemical spills, or equipment malfunction could create similar patterns. However, this theory struggles to explain the combination of factors: the precise circular pattern, the documented high temperatures, the geometric hole arrangement, the correlation with documented storm activity, and the blast-effect pattern of plant damage. Agricultural chemicals typically don't produce such concentrated heat effects or geometric ground patterns. The laboratory analysis definitively rules out simple crop disease or herbicide damage.
06 Verdict
ANALYST VERDICT
The evidence strongly supports the conclusion that this ground trace was caused by a lightning strike during the violent storm of June 8-9, 1981. The physical characteristics—circular pattern of heat damage, ground depression with multiple holes in geometric arrangement, laboratory-confirmed high temperatures, reduced soil moisture, and blast effects on vegetation—are all consistent with documented lightning strike phenomena. The case is significant not for representing an unexplained anomaly, but rather as an excellent example of proper investigative methodology: timely site examination, sample collection, laboratory analysis, and correlation with meteorological data. GEIPAN's classification as 'B' (probable identification) appears well-justified. Confidence level: High (85-90%). This case demonstrates how natural phenomena can create striking ground traces that might initially seem mysterious without proper scientific investigation.
