How climate change is revealing, and threatening, thawing relics

(CNN)Since the scorching hot summer of 2006, almost 3,000 archaeological artifacts have appeared from the melting ice in Oppland, Northern Norway. Among them, an Iron Age tunic, a 1,500-year-old arrow and a 3,400-year-old shoe.

Here, a a glacier archaeology program called Secrets of the Ice is documenting the finds being made on local ice patches -- static or slow-moving ice fields that are ideal locations to find objects that were once lost in the snow.
Instead of having to dig like traditional archaeologists, Oppland's archaeologists simply survey areas of the ice, looking out for artifacts that have thawed.
