Archeologists discovered frozen artifacts in Norway on Thursday, November 26. The team found a total of 68 arrows used for reindeer hunting more than 6,000 years ago at the Langfonne ice patch in the Jotunheim Mountains north of Oslo, Norway’s capital city. The archeologists noted that the arrows originated from the Stone Age to the Medieval Period. The Holocene journal, where the study is published, states that remains of reindeer antlers, Iron Age scaring sticks for reindeer hunting, and a 3,330-year-old leather shoe from the Bronze Age are among the arrows found.

The arrows are in poor condition upon closer inspection, which leads researchers to believe that it was due to ice movement. As a result of global warming, the Langfonne ice patch has retreated by more than 70% since two decades ago. “With the ice now retreating due to climate change, the evidence for ancient hunting at Langfonne is reappearing from what is in essence a frozen archive”, Lars Pilø, an archaeologist from the Innlandet County Council and the study’s lead author said. “The ice melt, sad as it is, provides an unprecedented archaeological opportunity for new knowledge,” he added.
