Climate archaeologists working in the Swiss Alps have uncovered 4,000-year-old Bronze Age dairy processing sites revealed by rapidly melting glaciers. The find includes well-preserved wooden sieves, stone hearths, and ceramic vessels containing traces of fermented milk, providing the earliest evidence of high-altitude transhumance and cheese production in the region.
The discovery suggests that ancient pastoralists adapted to environmental history shifts by utilizing alpine pastures much earlier than historical records indicated. Researchers are now racing against time to document these fragile organic remains before they decay due to atmospheric exposure caused by the retreat of the ice.
