Scientists Across The Globe Race To Study Five Specific Regions Before They Disappear

"There is obviously a crisis," said Lee, an environmental archaeologist with the Institute of Arctic and Alpine Research at the University of Colorado, Boulder. Wooden arrow shafts or food remnants are a treasure trove of information about how people lived in the early days of North American settlement. But organic items can crumble and blow away in the wind within a few weeks.
In the Yellowstone region, melting ice and snow recently uncovered what Lee said may be the world's oldest organic archaeological find from an ice patch: a dart shaft made from a birch branch about 10,000 years ago. A detailed mark on the shaft may be a clue to ancient social structures, and about how people first settled North America.
Across the Atlantic in Norway, Lars Holger Pilø and his team worked overtime last summer as a record heat wave melted snow and ice patches faster than ever. "We are losing the history of this landscape and we're trying save the history of this melting world," he said after a long trek to a site in July. "That work has to go on until the ice is gone."
Pilø said recovering artifacts from the melting snow and ice is like watching history in reverse at a dizzying clip, with ever-older finds. "It's going back from the bronze age to the stone age, and it's going so fast, it's not a good feeling. It's the great acceleration, with the landscape speeding into the past, but it's not reversing the way it would in a natural cycle. This is an anthropogenic landscape," he said.
