What have scientists discovered from the remains of the "iceman"?
One of the interesting points regarding the iceman is where he was found. It was about 10,000 feet altitude near an ancient mountain path. The glacier on top of the mountain had been retreating for some time; some may claim this had been due to general warming pattern occurring on the Earth now; for centuries (millennia?) this path was closed to hikers because it was actually under the glacier. However, in the iceman's day, 3000 years ago, the pass was open! This suggests that glacier expansion and contraction may have its own cycle, independent of the current glacial retreat, and therefore may not be due to global warming from recent industrial activity.
One thing scientists learned from the the 'Urtzi' iceman who was found on the Italian alp border, was how to be more careful in not making mistakes! They missed a tiny arrow-head stuck deep in his shoulder. This could have contributed to his death, as it may have festered, causing gradual sapping of his strength, causing him to need to rest in the icy mountains in a snowstorm.
Another thing they learned about was diet. He had recently eaten dried preserved meat and a crude sort of bread that was covered in hazel pollen. This taught them about dating stomach contents and pollen particles. They were able to tell the season he died in!
