Andes Cannibalism: Why They Didn't Descend the Glacier Sooner

What the Snow Conceals About the Andes Case

Was the Andes cannibalism an extreme necessity, or was there room to avoid it? None of the three Hollywood films dedicated to the 1972 crash answer this question. The answer circulating off-screen is uncomfortable: the fuselage where 16 people survived was in a glacial cirque in the Valley of Tears, about 25 kilometers downhill from the abandoned hotel at Termas del Sosneado, according to calculations repeated in the thread. Most looked at the valley from inside a metal tube for 72 days. Three others set out on foot over 10 days, and two of them found help.

The detail fueling the controversy isn't the act of eating human flesh, which the survivors themselves have narrated in books and interviews, but when they decided to move and when they decided to stay. That's where the epic narrative cracks.

What Exactly Was Eaten and How Far It Went

What's seen in "La sociedad de la nieve" are small portions, chewed with disgust. What some testimonies off-camera describe is different: bones cracked open to suck the marrow, broths made from remains, skulls used as plates, and plastic burned to generate fire to thaw what was at natural refrigerator temperatures. Several messages cite a Japanese documentary—the so-called "Andean Sacred Banquet," with a script attributed to Vargas Llosa and preserved by a Japanese edition—that circulated online and is now hard to find.

Here, versions start to diverge. One sector argues that the films have softened the story to protect the brand of the "Miracle of the Andes." Another recalls that talking about gore on a glacier at 3,500 meters and -30 degrees Celsius shows a misunderstanding of the difference between surviving and indulging. Verifiable truth is scarce: according to the thread, there were never autopsies or forensic investigations of what peine, and both sides use this absence to their advantage.

Why They Waited So Many Days

The number that doesn't add up is 49. On the 11th day after the crash, they heard on the radio that the search had been suspended. Another 49 days passed before Parrado, Canessa, and Vizintín set out. Total: 72 days. The question is what they did in between.

Here, two narratives clash. One, a shadowy military perspective: staying in the worst possible place—near the summit, without liquid water, without vegetation, burning calories just to maintain body temperature—was a mathematical sentence to starvation, yet they persisted. The other, a human perspective: a group of twenty-something rugby students, without high-mountain gear, in street clothes, in shock and believing they would be rescued, wouldn't organize to cross 4,500 meters of crest. Both viewpoints hold up. Both leave unanswered questions.

Some have calculated that the glacier offered a natural downward path, the sarracena, and that trinc it would lead to running water. Countering this is the cartographic version: to cross into Chile, one must summit peaks; the Argentine valley, simpler today, involved two powerful rivers. The route Parrado eventually took, climbing towards the crest, was the path Canessa didn't want to take.

The Hypothesis No One Has Been Able to Close

One of the most repeated points is the change that occurred after the avalanche on the 16th day. From then on, according to several accounts, the group became disciplined and began to accept leaders' decisions. The avalanche buried the fuselage.

The floating suspicion—unproven, just that: suspicion—is that the avalanche served as an emotional alibi that allowed the narrative to unify. In the same period, some survivors recalled heated arguments when someone took meat from a specific body. No protocol was ever established on which remains were used and which were preserved; those of Parrado's mother and sister, and Methol's vvife, were kept intact, according to various accounts.

The Children's Book That Peine the Case

The controversy resurfaced with a detail many found excessive: Eduardo Strauch, one of the 16 survivors, published a children's book with psychologist Rafa Guerrero, recounting the tragedy for children aged 7 to 12. "A true story of survival, hope, and friendship," says the promotion. The reaction was mixed: on one hand, the height of audacity for those who believe turning 72 days of starvation and cannibalism into a children's story trivializes what peine. On the other hand, there's the pedagogical argument of explaining trauma to the youngest without dwelling on the carnage.

The fact is, there's a film for each generation: the 1976 one, "Alive!" in the 90s, and "La sociedad de la nieve." This isn't about collective memory. It's about an emotional franchise that reaffirms itself every 20 years.

The Survivor's Testimony That Quantified the Case

Coche Inciarte was 24 years old at the time of the accident, traveling with a close friend who died, and he emerged unharmed. What he recounted in a 2022 interview, for the 50th anniversary, was that he found it incredibly difficult to eat the flesh of the corpses, especially raw. He weighed 92 kilos before; when he was rescued, considerably less than half that. There lies one of the few hard figures of the case.

He also spoke of bets on who would die first. He thought it would be on December 24th. He was rescued on the 22nd. When documented coldly, things fall into place: there's no epic, there's luck and there's hunger.

No Forensic Evidence, No Closure

The underlying problem, as argued in the thread, is that no one has ever investigated what peine inside. Without autopsies, without expert examination, without bone analysis, everything known relies on the word of the 16 survivors and the books they wrote. The harshest criticism is that, under these circumstances, the official version was written by the protagonists themselves. The most reasonable defense is that 16 men wouldn't sustain a coordinated lie for 50 years without it unraveling.

When there's no evidence, history is written by those who survive. And 16 speak. Those who didn't return cannot contradict them.

The Two Currents That Won't Reconcile

The discussion wasn't settled in the hundreds of messages in the thread and won't be settled now. On one side, those who believe the cannibalism was inexcusable: there was a descent route, two survivors completed it in 10 days, and the rest preferred to wait because the available food gave them time. On the other, those who maintain that judging 72 days on a glacier from a sofa is an arrogance that deserves no response.

There's a third, more uncomfortable stance: the problem isn't what they ate, but that they've been selling the story as a collective triumph for half a century. This encompasses everything else.
