Hidden History Revealed By Receding Glaciers
The rise in Earth's temperature is making snow lines and glaciers recede on mountain ranges all over the world. While this is a worrying trend, it's revealing hidden bits of history to archaeologists.
In Norway, the receding Lendbreen glacier at 6,560 feet above the sea level has revealed an ancient wool sweater dating to the Iron Age. Carbon dating has revealed that it's 1,700 years old. It was made of sheep and lamb's wool in a diamond twill, and was well-worn and patched from heavy use. The Norwegian research team estimates that the person who wore it would have been about 5 feet, 9 inches tall.
The results of the study have recently been published in the journal Antiquity.
This isn't the first discovery thanks to receding glaciers. The most famous, of course, is the so-called "Iceman", a well-preserved corpse of a man who died in the Alps around 3300 BC. Last year we reported the discovery of the bodies of soldiers from World War One in the Alps. in Norway, about 50 textile fragments have been recovered in recent years, although the sweater is the first complete garment.
Most discoveries have been accidental, with hikers and mountaineers reporting their finds to the appropriate authorities. In the Iceman's case, people originally wondered if the well-preserved body might have been a recent murder victim!
So if you're hiking near a melting glacier, keep an eye out for ancient artifacts and bodies, and remember that it's illegal to pocket them. Do science a favor and call a park ranger.
