You have to walk up a bit here, but it's worth it 🐾 Since their discovery in 1934 by Heinz Kohler, archaeologists have found more than 10,000 stone tools here. They are between 13,500 and 24,000 years old, so they come from a time when a thick layer of ice covered the central plateau and mammoths roamed the ice-free tundra.
