Cerro Uritorco / Huella del Pajarillo (Capilla del Monte) documented-hoax
Argentina's most famous UFO case — a luminous-object sighting and a large oval
burned mark ('Huella del Pajarillo,' widely cited ~120 m × 64 m) on a slope below
Cerro Uritorco — whose physical mark is genuinely documented but whose
extraterrestrial interpretation was endorsed by the municipality for tourism within
weeks, amplified by a TV reporter whose cameraman later confessed the coverage was
staged.
Uritorco is the corpus's Argentine keystone and its cleanest study of TOURISM-DRIVEN
myth-manufacture: a real, mundane physical mark (most plausibly a lightning fire
from a documented storm) reframed as a UFO landing by the municipality in three
weeks — before any forensic analysis — and inflated into a national phenomenon by
Nuevediario coverage the cameraman later admitted was fabricated. It is the
media-is-the-story counterpart to Voronezh, and the engine of a UFO/New Age tourism
economy (the annual Festival Alienígena) that the case literally created.
Timeline
1986-01-09
During a documented thunderstorm, ~10 PM, a family at a rural property reports a
luminous round object with 'little windows' emitting red light over the Pajarillo
slope below Cerro Uritorco.
witnesses: Gabriel Gómez (~12) · his grandmother Esperanza/'La Negra' Ponce-Gómez · great-aunt Sara
primary source: Ricardo González (proponent account); Vice
1986-01-10
A large oval mark of burned grass (~120 m × 64 m; some sources ~100 m) is found
on the SE slope of Cerro El Pajarillo; locals initially attribute it to a
lightning strike from the storm.
witnesses: local residents
primary source: Agostinelli (Factor blog); prensamercosur
1986-01-27
The municipality issues a document officially endorsing the UFO explanation —
within three weeks, before any forensic soil analysis was requested.
witnesses: Mayor Diego Sez · Tourism Sec. Jorge Suárez
primary source: Agostinelli (Factor blog)
1986
Nuevediario reporter José de Zer (José Bernardo Kerzer) and cameraman Carlos
'Chango' Torres produce sensational TV segments ('¡Seguime, Chango!'), turning
the site into a national phenomenon.

In Página/12 ('El equipo de José'), cameraman Chango Torres confesses the coverage
was fraudulent: 'The stain was real, but everything else was pure fiction' —
staged insects, painted cave drawings, nail-polish 'alien' rocks, a faked summit
camp, flashlight/cigarette 'lights.'
witnesses: Carlos 'Chango' Torres · journalist Mariano Blejman

Named personnel
- The Gómez family — The witnesses to the luminous object (boy Gabriel Gómez, his grandmother, great-aunt Sara) rank at time: primary witness to: the claimed object over the Pajarillo slope
- Mayor Diego Sez & Tourism Sec. Jorge Suárez — Municipal officials who endorsed the UFO explanation within three weeks, before any forensic analysis rank at time: role: the official myth-endorsement
- José de Zer & Carlos 'Chango' Torres — The Nuevediario reporter and cameraman who made the case a national sensation; Torres confessed in 2002 that the coverage was staged rank at time: role: the media fabrication
- Alejandro Agostinelli — Argentina's leading UFO historian; argued lightning-strike-plus-reframe and documented the instant municipal endorsement and absence of any fire analysis rank at time: role: the skeptical investigation
- Ricardo González — Argentine ufologist and principal proponent of the extraterrestrial-landing interpretation rank at time: role: the pro-anomaly promoter
Object — reported
shape
claimed: a round/flat object 'like a ball' with windows, red light and shifting white fluorescent lines; documented: a large oval of burned grass
size
the burned oval commonly cited ~120 m × 64 m (Wikipedia: ~100 m); visible for years
surface features
proponent-claimed anomalies (grass scorched only on top — 'heat from above'; a nearby willow yellowed; the mark allegedly untouched by a 1987 forest fire) — none from any forensic report
observed behaviors
- the burned mark is genuinely real (affirmed even by the fraud confession)
- the UFO interpretation was endorsed by the municipality in three weeks with no forensic analysis
- the national TV coverage was confessed (2002) to be largely staged — fake lights, planted artifacts
Theories that invoke this case (3)
The promoted interpretation — an extraterrestrial craft landing that scorched the slope — recorded to mark the claim that rests entirely on proponent assertions with no surviving forensic report.
The corpus's leading reading: a real, mundane mark reframed as a UFO landing for tourism within weeks and inflated by confessed-fabricated TV coverage — manufactured belief and a tourism economy built on it.
The most-supported physical reading of the mark itself: a lightning strike during the documented 8-9 January storm igniting the grass (an aerial photo shows a 'V'-shaped electrical-impact pattern) — before any UFO framing.
Theories that do NOT invoke this case — and why
a landing-trace/media case, not a creature record
no associated exotic phenomenology — the mark resolves to fire and the coverage to fabrication
a tourism-driven local myth, not part of any government-disclosure arc
Conventional explanations advanced — and their status
Lightning strike igniting the grass, then reframed as a UFO
proponents: Alejandro Agostinelli
The best-supported skeptical reading: a documented storm, a 'V'-shaped mark consistent with electrical-impact fire, and no forensic analysis ever conducted — the mark is real and mundane, the UFO framing added afterward.
Deliberate hoax / staged for tourism
proponents: firefighter Luis Bartoli · implied by the instant municipal endorsement · Chango Torres's 2002 confession
Strong for the MEDIA layer: the coverage was confessed fabricated, the town endorsed the UFO story in three weeks, and authorities never requested the soil/fire analysis protocol would require.
A genuine extraterrestrial landing trace
proponents: Ricardo González · J.J. Benítez · Jiménez del Oso
The pro-anomaly reading; the claimed anomalies (heat-from-above, yellowed willow, surviving the 1987 fire) are single-source proponent assertions, never independently verified.
Where further investigation has leverage
- The central evidentiary gap: no forensic soil/heat analysis of the mark was ever performed (lightning vs deliberate burn remains formally unresolved).
- The 2002 Página/12 confession detailing the staged coverage.
- Agostinelli's documentation of the storm, the 'V'-shaped mark, and the instant municipal endorsement.
Corpus status
documented-hoax
Held documented-hoax (defensible secondary: historically-pivotal-explained). The
strongest evidence points to a real fire — most plausibly a lightning strike during
the documented 8-9 January storm — that was immediately and deliberately reframed as a
UFO landing for tourism, formalized by the municipality within three weeks with no
forensic investigation, then nationally inflated by Nuevediario coverage the cameraman
later confessed was fabricated. The physical mark is genuine, but its extraterrestrial
interpretation rests entirely on proponent claims with no surviving forensic report,
against a documented confession of staged media and overwhelming tourism incentive.
Honest caveat: the mark's physical origin (lightning vs deliberate burn) was never
forensically settled — the hoax is the UFO interpretation and the coverage, not
necessarily the burn.
