Death on Aconcagua

Aconcagua mountain presents a formidable challenge for even the most experienced climbers due to its extreme elevation and harsh environment, which often lead to serious physical and psychological effects.

The extreme elevation and harsh environment of Aconcagua pose significant risks and difficulties for climbers.

Aconcagua is the highest mountain outside of Asia, with a summit over 22,800 feet above sea level, resulting in drastically reduced oxygen levels that can severely impair the human body.

The human body starts to struggle at high altitudes due to the low oxygen levels, which can cause symptoms of altitude sickness such as severe headaches, fatigue, dizziness, sleep issues, vomiting, loss of coordination, and mental fog. In severe cases, altitude sickness can lead to fluid around the lungs or brain swelling—conditions that could be deadly without immediate descent to lower elevations, as experienced by Petroski.

The mountain's glacier, penitentes (towering ice formations), and unpredictable weather make the climb technically challenging and dangerous, even for experienced mountaineers.

Climbers attempting the Polish route on Aconcagua must scale a nearly vertical glacier, navigate fields of towering ice formations known as penitentes, and prepare for false summits that appear like "cruel mirages." They encounter fine powder on the glacier, which can hamper progress by sinking climbers waist-deep. Even experienced mountaineers like Janet Johnson, who had summited all 50 peaks over 14,000 feet in Colorado and Kilimanjaro, are not exempt from these challenges, as the environment at such altitudes can push the human body and psyche to their limits.

The expedition lacked the modern safety equipment and support that climbers rely on today.

Without GPS trackers, radios, oxygen, or reliable rescue services, the climbers had to rely solely on their own resources and the assistance of their fellow team members.

The interpersonal relationships within the climbing team raise several concerns about their dynamics and leadership, potentially contributing to their tragic experience.

The group exhibited a lack of cohesion and teamwork, which may have contributed to the tragic outcome.

From the outset, the team, made up of climbers from different cities and backgrounds, lacked a sense of camaraderie and unity, which are crucial for the success and safety of mountaineering expeditions. They were strangers, coming together for a shared goal but without any established cohesion or trust amongst them. The guide, Miguel Alfonso, though highly experienced, wasn't seen as the authoritative leader he needed to be.

The climbers were largely strangers to one another, coming from different cities and backgrounds, and did not defer to the guide as a clear leader.

The climbers, including Cooper, Johnson, Zeller, and McMillan, tackled the dangerous climb not as a cohesive unit but as individuals. At their final camp before the summit attempt, there remained an absence of team spirit. Alfonso was treated more as hired help than the leader. This lack of clear leadership and teamwork was evident and posed a significant risk in the extreme conditions of the mountain climb.

There were tensions and complaints within the group, such as Cooper's criticism of Johnson's perceived lack of effort.

Cooper expressed in his journal that Johnson was not contributing fairly to the group's efforts and seemed only interested in reaching the summit, relying on others to assume the bulk of the work. This criticism indicated underlying tensions within the group, further fracturing their already weak unity.

The group's dysfunction and self-interest may have affected their decision-making and actions on the mountain.

The lack of teamwork affected not only the group dynamics but also their decision-making and actions when faced with adversity on the mountain.

The mystifying deaths of John Cooper and Janet Johnson on Aconcagua continue to spark debate and speculation due to inconclusive official investigations and theories of foul play.

The official investigations were inconclusive and left many unanswered questions

Despite the completion of autopsies three years after the tragic events of 1973, the Argentine authorities were unable to determine a clear cause of death for Cooper and Johnson. Their efforts were hindered by conflicting witness accounts and the delay in recovering the bodies. The case was further disrupted when a military coup in Argentina in 1976 halted the judicial process, preventing any official determination of the events on Aconcagua.

This cessation of the investigation, combined with the deaths of the involved parties, means that there will never be a formal trial to conclusively address the climbing accident. An Argentine police officer acknowledged the unreliability of the witness statements, noting the effects of altitude could make their accounts seem hallucinatory. Consequently, the case relied on the hard evidence presented by the bodies' conditions at the time of discovery.

The official cause of death for Cooper pointed to cranial contusions, a finding corroborated by the medical examiner's report on Johnson's body, which also indicated major head trauma. This clear evidence of head injuries suggested a different narrative from the initial theories of a mere climbing accident conceived amid altitude-induced confusion and perilous conditions.

Furthermore, Cooper's body was notably found with a bleeding abdominal wound, a missing crampon, and ice axe. Johnson's body presented an equally concerning scene, as she lay with a rock placed on her face, sliced footwear, and similarly missing equipment.

Alternative theories suggest the possibility of foul play

The possibility of foul play has persisted for a long time due to numerous details that are inconsistent with typical climbing accident injuries. A climber familiar with Aconcagua pointed out that given the soft snow conditions and the relatively flat area where the bodies were found, a fatal fall seemed unlikely. The specific injuries to Cooper and Johnson, such as the precise hole in Cooper's abdomen and the rock on Johnson's face, introduced the question of whether their deaths were intentional acts of murder rather than accidental. ...

The condition of the bodies of Cooper and Johnson has raised serious questions about the nature of their deaths, with the autopsies revealing details that suggest a scenario more complex than accidental death.

The autopsies revealed that Cooper and Johnson died from blunt force trauma to the head, rather than from exposure or falls.

The medical examiner and their team found that the head injuries Cooper and Johnson suffered were the result of blunt force trauma, indicating they were killed. This is further complicated by details like Cooper's abdominal wound, which was a deep, round hole penetrating to his spine. This wound was not typical of a standard fall but was more consistent with being caused by a sharp tool like an ice screw, commonly used in ice climbing. The hole, described as symmetrical, was actively bleeding when Cooper died, suggesting it occurred while he was still alive.

Johnson's body showed signs of heavy blows to her face with protruding bone and a clearly broken nose. A rock was deliberately placed on her face, an action that stands out because there were no other rocks in the vicinity, suggesting intent rather than a random occurrence. Furthermore, her boot was sliced open, with cuts that appeared clean, as though caused by an axe rather than ragged rips from friction against a sharp rock.

The lack of other significant injuries on the bodies casts doubt on the plausibility of accidental deaths.

The examination of the bodies revealed specific trauma to their faces and heads, with no other abrasions, inconsistent with typical injuries sustained in climbing accidents. These findings are supported by experienced climbers, who noted that the specific nature of the injuries was not ...
