‘This is not just long-range but ultra-long-range transport of raw materials.’ This Great Ice Road was in operation four times as long ago as the famous Silk Road in Central Asia, and it was twice as old as the Egyptian pyramids.

As the crow flies this is a journey of some 1,500 km but as scientist Yaroslav Kuzmin told us ‘the actual distance that obsidian ‘walked’ is at least 2,000 km.

‘Dog-sled technology undoubtedly played an important part in raw materials exchange networks, as evidenced by the presence of Chukotka obsidian at the Zhokhov site.

‘Although virtually no obsidian has been found in the Early Holocene archaeological record between the Zhokhov site and Chukotka, a connection between these two areas clearly existed by c.

They conclude: 'Early Holocene super-long-distance obsidian exchange in the High Arctic is now scientifically demonstrated.

Sea level was more than 100 metres below present making that location accessible.The conclusion is that ancient people used dog sleds to cover these remarkable distances 'at the ends of the earth'.At the time Zhokhov Island - now part of the De Long Islands in the New Siberian archipelago - was connected to the Siberian mainland, and the climate was milder than today. Obsidian was used by ancient people at a famous site on Zhokhov for tools: the black or green volcanic glass, an extrusive igneous rock, was a material of choice.‘The archaeological data from Zhokhov therefore indicate a super-long-distance Mesolithic exchange network,’ conclude the international team of researchers in the Antiquity paper.The scientists doubt the ancient people themselves carried the obsidian all this way.
