The discovery of obsidian tools on Zhokhov island indicates the existence of a vast trading network in prehistoric deep Arctic 9,000 years ago. Prehistoric Siberians living on an island in the Arctic Circle around 8,000 to 9,000 years ago possessed obsidian tools that hailed from 1,500 kilometers (932 miles) away, Russian archaeologists reported in the journal Antiquity last week. To people living on icy Zhokhov Island, the closest known source of obsidian – a shiny glassine volcanic rock that shatters to create extremely sharp blades – is near Lake Krasnoye in the lower reaches of the Anadyr River in Chukotka. Krasnoye is 1,500 kilometers as the bird flies from Zhokhov. As the sled dog trudges, it’s more like 2,000 kilometers, the team headed by Vladimir Pitulko of the Russian Academy of Sciences reports.
