Discovery of 5,300-year-old Iceman Ötzi marks 35th anniversary since Alpine find

Discovery on the Tisenjoch ridge

On 19 September 1991, German hikers Helmut and Erika Simon from Nuremberg were descending in the Austrian-Italian border region when they strayed off the marked path. In a hollow at the Tisenjoch in the Ötztal Alps, at an elevation of roughly 3,200 metres, they found a human upper body protruding from the glacial ice. Rescuers and local authorities initially suspected the corpse belonged to a modern hermit or a missing soldier from wartime. The remains were freed from the ice using tools including an ice axe. Early estimates on site suggested the body had been buried for decades or a few centuries, but subsequent examinations quickly altered that timeline.

The man grew older by the hour.

Initial investigation and storage in Innsbruck

Laboratory analysis of the corpse and its equipment, including a copper axe, an unfinished bow, and a dagger, established that the body was approximately 5,300 years old, dating to the Neolithic period. The public announcement caused immediate global media attention, overwhelming the discoverers at their home in Germany.

It was so bad that we no longer answered the phone.

The extreme age of the remains also resolved official legal proceedings surrounding the discovery. Judge Günther Böhler opted not to order a conventional autopsy or initiate a formal criminal investigation.

It was clear that there was no perpetrator who could still be investigated.

For nearly seven years, the 13.3-kilogram body was kept at the Institute of Anatomy in Innsbruck under conditions mimicking the glacier, held at minus 6 degrees Celsius with very high humidity, and examined briefly once per month.

Border determination and exhibition in Bolzano

Innsbruck served as a temporary research base until official land surveys resolved the exact jurisdiction of the find. Surveyors determined that the discovery site lay approximately 92 metres south of the Austrian border on Italian territory, within the province of South Tyrol. In January 1998, authorities moved the mummy from Innsbruck to Bolzano under strict security measures. The body was placed in a purpose-built cold chamber at the South Tyrol Museum of Archaeology. Public exhibitions began in March 1998, allowing visitors to view the glacier corpse behind protective glass under dimmed lighting.

Forensic findings and natural preservation

Subsequent medical and criminal examinations provided detail about the man's final days. Forensic pathologist Oliver Peschel and profiler Alexander Horn analysed a deep wound between Ötzi's thumb and index finger, identifying it as a defensive injury sustained about two days before his death. The hunter appeared to have survived that altercation without lasting alarm, as his bow remained unstrung and only two of his arrows were fitted with points when he was fatally shot in the shoulder by an arrow and bled to death. Glaciologist Georg Kaser explained that the body fell onto a deep layer of snow and settled onto a large boulder at the edge of the glacier, avoiding destructive ice streams. The tissue became waxy after 1,500 years of alternating exposure to ice, water, and sun, followed by 3,800 years encased in a sealed ice capsule. Researchers later identified ibex DNA and hop hornbeam pollen in his stomach, reconstructing a farmer with rheumatism and gallstones who wore bear-leather shoes and carried a tinder fungus for fire making.
