Climate change is exposing reindeer hunting gear used by the Vikings' ancestors faster than archaeologists can collect it from ice thawing in northern Europe's highest mountains.
"It's like a time machine...the ice has not been this small for many, many centuries," said Lars Piloe, a Danish scientist heading a team of "snow patch archaeologists" on newly bare ground 1,850 meters (6,070 ft) above sea level in mid-Norway.
Specialized hunting sticks, bows and arrows and even a 3,400-year-old leather shoe have been among finds since 2006 from a melt in the Jotunheimen mountains, the home of the "Ice Giants" of Norse mythology.
As water streams off the Juvfonna ice field, Piloe and two other archaeologists -- working in a science opening up due to climate change -- collect "scare sticks" they reckon were set up 1,500 years ago in rows to drive reindeer toward archers.
