The bodies of two Belgian climbers who vanished in the Swiss Alps 34 years ago have been formally identified, police confirmed on July 26, after their remains were discovered in the melting Trift Glacier near the Italian border.
A hiker reported the discovery of the two bodies on the glacier in southern Switzerland, prompting authorities in the Wallis canton to transport the remains to the Institute of Forensic Medicine at Wallis Hospital in Sion for identification. Officials stated that a direct comparison of DNA profiles confirmed the identities of the mountaineers, who disappeared in the Weissmies region in 1992.
The two men were 39 and 41 years old at the time of their disappearance. Their remains were preserved in the glacier until recent melting exposed them, according to regional police.
Glacier retreat reveals decades-old remains
Wallis police maintain a missing persons registry dating back to 1925, primarily tracking cases in high-altitude and riverine environments. Authorities noted that the retreating ice has increasingly revealed remains of individuals who vanished decades ago.
"Due to the retreat of glaciers, the remains of people who disappeared in the mountains several decades ago are repeatedly revealed," police said in a statement. This phenomenon has been linked to climate change, which has accelerated glacial melt worldwide.
Recent cases of glacier-recovered remains
The discovery follows several high-profile cases in which melting glaciers have released long-lost remains:
- In 2024, the body of an American mountaineer was found 22 years after his disappearance while climbing a peak in Peru.
- In 2025, the remains of a British researcher who vanished in 1959 in Antarctica were recovered near a receding glacier on King George Island.
- Also in 2025, the body of a missing man was discovered on a melting glacier in Pakistan, 28 years after he went missing.
- In 2024, the bones of a Swiss mountaineer who disappeared in 1994 were found on the Ober Gabelhorn glacier in Wallis.
- Earlier, the remains of a German climber who vanished in 1986 were recovered on a glacier in the Swiss Alps.
Officials emphasize that the Trift Glacier’s retreat is a direct consequence of rising global temperatures, which have significantly reduced glacial mass in the Alps over recent decades. The Swiss Federal Office for the Environment has documented a loss of approximately 10% of glacier volume in the past decade alone, with projections indicating continued acceleration in melt rates.
Impact on search and recovery efforts
The discovery underscores the challenges faced by search and rescue teams in alpine regions, where traditional methods of locating missing persons are increasingly complicated by environmental changes. While glacial melt has aided recovery efforts in some cases, it has also introduced new risks, including unstable terrain and unpredictable ice movements.
Authorities in Wallis have not announced plans to expand search efforts in the region but reiterated the importance of the missing persons registry as a tool for future identifications. The case remains closed following the DNA confirmation, though the circumstances of the climbers’ disappearance in 1992 remain unpublicized.
For families of missing mountaineers, the discovery offers both closure and a reminder of the enduring risks posed by high-altitude expeditions amid a warming climate.
