His skin, hair, bones, and organs were cryopreserved in time, allowing archeological researchers a phenomenal insight into human life in the Copper Age. The frozen corpse also gave modern science the opportunity to forensically investigate and positively determine how Otzi the Iceman was killed. The story began on a sunny September day, when two hikers were traversing a mountain pass at the meter 10, foot level and saw a brown, leathery shape protruding from the ice amidst running melt-water.

Examining closely, they found a human body which they thought might be the victim of Scientific dating techniques used on otzi the iceman past mountaineering accident. The hikers reported it to Austrian police who attended the following day and quickly realized they were dealing with an ancient archeological site. A scientific team was assembled and, over a three-day period, the remains were extracted and taken to the Institute of Forensic Medicine in Innsbruck.

Such an incredibly valuable find soon led to a jurisdictional argument between the Austrian and Italian governments and an immediate border survey was done, finding Otzi had been lying ninety-two meters inside of Italian territory. Italy gained legal possession of the body and artifacts, however in the interests of science and history, everything was kept at Innsbruck until a proper, climate-controlled facility was built at the South Tyrol Museum of Archaeology in Bolzano, Italy, where Otzi the Scientific dating techniques used on otzi the iceman now rests.

Where did he come from? How long ago did he live? And, of course, what caused his death?

Otzi was found lying face down with outstretched arms in a protected rock depression near the Finail Peak watershed at the top of the Tisenjoch pass which connects two forested valleys. The trench measured 40 Scientific dating techniques used on otzi the iceman foot long, between 5 and 8 meters foot wide, and averaged 3 meters 10 feet deep. For millennia, this area was covered by glaciers which, by the end of the twentieth century, had receded.

Four separate scientific institutes conducted C radiocarbon dating on Otzi, equivocally agreeing he came from between and BC -- more than 5, years ago. This was the oldest-known preserved human being; far older than the Egyptian and Inca mummifications or the corpses found pickled in peat bogs. Something exceptionally unique about Otzi was that he was a "wet" mummy -- an almost unheard of process for a cadaver of this age where humidity was preserved in his cells, unlike the intentional dehydration processes used in Egypt and Peru.

As well, Otzi was perfectly intact and not dissected or embalmed by a funeral ritual. His entire body achieved a state of elasticity and, although shrunken, remained as in the day he died including vital clues stored in his digestive tract. Researchers felt Otzi must have Scientific dating techniques used on otzi the iceman preserved through a chain of coincidences. Secondly, the gully lay perpendicular to the main ice flow, allowing the grinding action of the glacier to pass overtop.

Thirdly, exposure to air and sunlight was only a brief period before being found by the hikers. It was vital Otzi remain frozen to avoid an irreversible decomposition and remain intact to preserve his historical significance. This gave researchers limited ability to examine the cadaver as would be done in a conventional autopsy.
